Summary:
This diff makes sure that devices will actually instantiate applicable sandy device plugins. Similar to how client plugins are owned by Client, device plugins are directly owned by BaseDevice, which significantly simplifies life cycle management and doesn't dispatch updates to all Redux connect components whenever something irrelevant changes.
Also made sure `device.teardown()` is called. That API already existed, but wasn't used or implemented before.
Updated Flipper test utils to support testing device plugins as well (both Sandy and classic ones)

Summary:
This stack introduces Sandy device plugins, they are quite similar to normal plugins, but, a devicePlugin module is organized as
```
export function supportsDevice(device): boolean
export function devicePlugin(devicePluginClient)
export function Component
```
Device plugins get access to the device meta data and can subscribe to the `onLogEntry` callback and `onDestroy` lifecycle.
They will be able to store state just as normal plugins, but can't send or receive methods, so devicePluginClient is a bit limited.
This diff only sets up most of the new data structures, and makes sure everything still compiles and no existing tests fail.
To prevent this diff from becoming to big, actually loading, rendering and testing device plugins will be done in next diffs
Please take a critical look at the api proposed and the (especially) the public names used :)

Summary:
This adds support for handling incoming deeplinks in a Sandy plugin, which can be done by using a `client.onDeepLink(deepLink => { } )` listener
Also generalized deeplinks to not just support strings, but also richer objects, which is beneficial to plugin to plugin linking.

Summary:
This diff makes sure Sandy plugins show up as well in the plugin selector when making exports (and in support form as well).
Also verified that this works with the Sandy updated section plugin.
Note that persisted state now didn't need any changes in the plugin code to work :)
Commented / simplified the calculation of available plugins a little bit and fixed a confusing issue where two different redux stores where created in one unit test, which caused an issue in the new implementation.

Summary:
Made Sandy plugins part of the export / import logic
Note that in the export format there is now a `pluginStates2` field. It could have been put in `pluginStates` as well, but I started with that and it felt very weird, as the `pluginStates` are supposed to reflect what is living in the Redux stores, where sandy state doesn't live in the Redux store (not directly at least). Trying to store it in the same field made things overcomplicated and confusing.

Summary:
This plugin adds serialization capabilities to Sandy plugins buy setting the a `persist: <key>` flag. This shouldn't be used for state that is unserializable, too big, too sensitive, or irrelevant during export / import.
Using an explicit `persist` flag is done to make plugins robust to changes over time; as long as the key is kept the same, state variables can be renamed and reordered without breaking the import / export format. Also it allows us to detect some changes in the import / export format and warn about it.
Alternative designs considered but not implemented would be:
1. requiring the user to explicitly return the state from the factory (e.g. `const todos = createState([]); return { todos }`,
2. or construct the state from client (e.g. `const todos = client.createState([])`)
3. enable persistence by default, and store states in the order the states were created (much like useState in React). This was implemented in the first versions of this diff, but as pointed out in the discussions, this is too sensitive too (accidental) format changes, as the storage format would be quite implicit
A nice benefit of the current approach, especially compared with alternative approach 1, is that state being restored is immediately visible in the plugin factory. In other words, directly after initialization `const todos = createState([])`, the `todos.get()` is actually set to the state that is being restored, rather than having still the initial state which is only overridden rather. So this behaves very much like the `useState` hook in React.
Furthermore, in the future we could use the same `persist` key in combination with other options, such as `saveToLocalStorage`, in case some state acts as a 'preference' (T69989583).
`TestUtils.startPlugin` supports starting plugins with an initial state by using the optional `initialState` field
Actually wiring up the serialization and deserialization into the export / import functionality of Flipper is done in the next diff.

Added unittests have been added as well. The UI snapshots in there are kinda overkill, but nice demo that it works.
This completes the full roundtrip of the new Sandy infra, so this will be the last diff of this stack. I promise. I think.

Summary:
Introduced a minimal state abstraction so that state can be maintained in the plugin instance, but subscribe to by the UI.
At a later point we could pick an off the shelve solution like Recoil or MobX, or introduce cursors to read something deep etc etc, but for now that doesn't seem to be needed at all, and I think this will be pretty comprehensible for plugin authors (see also the 25th diff in this stack).
The api
```
createState(initialValue): Atom
Atom {
get() // returns current value
set(newValue) // sets a new value
update(draft => { }) // updates a complex value using Immer behind the scenes
}
// hook, subscribes to the updates of the Atom and always returns the current value
useValue(atom)
```

Summary:
This sets up the initial infra that is to be used by plugin devs to test plugins.
There is not much yet to see, as there is no state or message sending yet. But at least the life cycle of plugins can be test, things are strongly typed and everything is in the place where it should be :)
N.b. the import difference with these utils and the createFlipperMock utilities in Flipper are
1. this testing infra is entirely inside flipper-plugin package, so that plugin devs don't need flipper as a dependency
2. this testing infra doesn't provide abstractions for plugin / device / client switching; it tests plugins purely in isolation of the rest of the world (except for firing `onConnect` / `onDisconnect` which is normally the effect of switching plugins)

Summary:
Introduced hooks that are called whenever the plugin is connected / disconnected to it's counter part on the device.
There is some logic duplication between `PluginContainer` for old plugins, and `PluginRenderer` for new plugins, mostly caused by the fact that those lifecycles are triggered from the UI rather than from the reducers, but I figured refactoring that to be too risky.

Summary:
This diff makes sure sandy plugins are initialized.
Sandy plugins are stored directly in the client for two reasons
1. we want to decouple any plugin state updates from our central redux store, as redux is particularly bad in handling high frequency updates.
2. The lifecycle of a plugin is now bound to the lifecycle of a client. This means that we don't need 'persistedStore' to make sure state is preserved; that is now the default. Switching plugins will no longer reinitialize them (but only run specific hooks, see later diffs).
3. PersistedState will be introduced for sandy plugins as well later, but primarily for import / export / debug reasons.
A significant difference with the current persistent state, is that if a client crashes and reconnects, plugins will loose their state. We can prevent this (again, since state persisting will be reintroduced), but I'm not sure we need that for the specific reconnect scenario. Because
1. we should fix reconnecting clients anyway, and from stats it looks to happen less already
2. reconnects are usually caused by plugins that aggregate a lot of data and get slower over time. Restoring old state also restores those unstabilites.
For the overview bringing back the archi picture of earlier diff:

Also fixed a bug where enabling background plugins didn't enable them on all devices with that app.

Summary:
So far there were 2 types of plugins: `FlipperPlugin` and `FlipperDevicePlugin`. This introduces a third kind: `SandyPluginDefinition`.
Unlike with the old plugins, the export of the module is not directly exposed as the plugin definition. Rather, we use class `SandyPluginDefinition` (instance) that holds a loaded definition and its meta data separately (`PluginDetails`). This means that we don't have to mix in and mutate loaded definitions, and that for unit tests we can avoid needing to provide a bunch of meta data. This also prevents a bunch of meta data existing on two places: on the loaded classes as static fields, and in the meta data field of the loaded class as well. Finally, we can now freely extends the `PluginDetails` interface in flipper, without needing to store it on the loaded classes and we are sure that no naming conflicts are caused by this in the future.
For compatibility with the existing code base, common fields are delegated from the `SandyPluginDefinition` class to the meta data.
Also cleaned up types around plugins a little bit and removed some unnecessary casts.
For all features that reason about plugins in general (such as exports), sandy plugins are ignored for now.
`SandyPluginInstance` is worked out in further diffs
The `instanceof` calls are replaced by a utility function in later diffs.
