Summary:
Sorry for long diff! I can try to split it if necessary, but many changes here are 1-1 replacements / renames.
**Preambule**
Currently we bundle default plugins into the Flipper main bundle. This helps us to reduce bundle size, because of plugin dependencies re-use. E.g. if multiple plugins use "lodash" when they are bundled together, only one copy of "lodash" added. When they are bundled separately, the same dependency might be added to each of them. However as we're not going to include most of plugins into Flipper distributive anymore and going to rely on Marketplace instead, this bundling doesn't provide significant size benefits anymore. In addition to that, bundling makes it impossible to differentiate whether thrown errors are originated from Flipper core or one of its plugins.
Why don't we remove plugin bundling at all? Because for "dev mode" it actually quite useful. It makes dev build start much faster and also enables using of Fast Refresh for plugin development (fast refresh won't work for plugins loaded from disk).
**Changes**
This diff introduces new option "no-bundled-plugins" for "yarn start" and "yarn build" commands. For now, by default, we will continue bundling default plugins into the Flipper main bundle, but if this option provided then we will build each default plugin separately and include their packages into the Flipper distributive as "pre-installed" to be able to load them from disk even without access to Marketplace.
For "yarn start", we're adding symlinks to plugin folders in "static/defaultPlugins" and then they are loaded by Flipper. For "yarn build" we are dereferencing these symlinks to include physical files of plugins into folder "defaultPlugins" of the produced distributive. Folder "defaultPlugins" is excluded from asar, because loading of plugins from asar archive might introduce some unexpected issues depending on their implementation.

Summary:
Pull Request resolved: https://github.com/facebook/flipper/pull/998
After this diff all the default plugins (which are distributed with Flipper) will be included into the main app bundle instead of bundling each of them separately and then loading from file system. This is done by auto-generating plugins index in build-time and importing it from Flipper app bundle, so Metro can follow these imports and bundle all the plugins to the app bundle.
This provides several benefits:
1) reduced Flipper bundle size (~10% reduction of zipped Flipper archive), because Metro bundles each of re-used dependencies only once instead of bundling them for each plugin where such dependency used.
2) Faster Flipper startup because of reduced bundle and the fact that we don't need to load each plugin bundle from disk - just need to load the single bundle where everything is already included.
3) Metro dev server for plugins works in the same way as for Flipper app itself, e.g. simple refresh automatically recompiles bundled plugins too if there are changes. This also potentially should allow us to enable "fast refresh" for quicker iterations while developing plugins.
4) Faster build ("yarn build --mac" is 2 times faster on my machine after this change)
Potential downsides:
1) Currently all the plugins are identically loaded from disk. After this change some of plugins will be bundled, and some of them (third-party) will be loaded from disk.
2) In future when it will be possible to publish new versions of default plugins separately, installing new version of such plugin (e.g. with some urgent fix) will mean the "default" pre-built version will still be bundled (we cannot "unbundle" it :)), but we'll skip it and instead load new version from disk.
Changelog: Internals: include default plugins into the main bundle instead producing separate bundles for them.
