5df34a337c Unshare global types
Summary:
This diff adds `types` fields on the compiler config for every project. This way we can make sure that for example node types and packages are not available in flipper-ui-core. Without an explicit types field, all types would be shared between all packages, and implicitly included into the compilation of everything. For the same reason `types/index.d.ts` has been removed, we want to be intentional on which types are being used in which package.

This diff does most of the work, the next diff will fine tune the globals, and do some further cleanup.

As an alternative solution I first tried a `nohoist: **/node_modules/types/**` and make sure every package list explicitly the types used in package json, which works but is much more error prone, as for example two different react types versions in two packages will cause the most unreadable compiler error due to the types not being shared and not literally the same.

279f3c41b7 Introduce shallow serialization
Summary:
Changelog: [Flipper] Improve serialisation mechanism format & speed

The default serialisation mechanism used by Flipper to serialise plugin states is very flexible, taking care of maps, sets, dates etc. However, it is also really slow, leading to issues like in the related tasks, and work arounds like D17402443 (98bc01618f) to skip the whole process for plugins.

This diff changes the serialisation mechanism to have a better trade off between speed and convenience: For now we will only apply the smart serialisation for objects living at the _root_ of the serialised object, but it won't be applied recursively.

This sounds like a dangerous change, but works well in practice:
* I went through all `persistedState` and `createState` definition (the types), and the idea that complex types like Map and Set only live at the root of the persisted state holds up nicely. That makes sense as well since plugins typically store literally the same data as that they have received over the wire, except that they put it in some maps, sets etc.
* I introduced `assertSerializable` that only runs in dev/test, which will check (recursively, but without all the cloning) to see if a tree is indeed serialisable.
* The fact that by swapping this mechanism rarely existing unit test for exportData needed changes proves that the assumption that only roots are relevant generally upholds (or that plugin authors don't write enough tests ;-)).
* I verified that popular plugins still import / export correctly (actually *more* plugins are exportable now than before, thanks to sandy wrapper introduced earlier)
