Summary:
Enabling Metro cache for dev mode. For release builds we reset the cache.
Cache is used for faster compilation in dev mode for both main and renderer bundles, as well as for plugins.
Currently we have few side effects based on env vars, so cache is invalidated when they are changed. Also the cache is invalidated when transformations are changed (changed code, bumped dependency etc). Also added a script to reset the cache if something is going wrong.

Summary:
SORRY FOR BIG DIFF, but it's really hard to split it as all these changes are cross-dependent and should be made at once:
1. Moved transformations to separate package "flipper-babel-transformer" and linked it using yarn workspaces to "static" and "pkg" packages where they are re-used. Removed double copies of transformations we had before int these two packages.
2. Converted transformations to typescript
3. Refactored transformations to avoid relying on file system paths for customisation (FB stubs and Electron stubs for headless build)
4. As babel transformations must be built before other builds - enabled incremental build for them and changed scripts to invoke the transformations build before other build scripts
5. As we need to deploy all the dependencies including the fresh "flipper-babel-transformer" as a part of "static" - implemented script which copies package with all the dependencies taking in account yarn workspaces (hoisting and symlinks)
