Summary:
This makes use of the new no-op package and also structures the app
into release and debug flavours that can be built with and without
Flipper part of the APK.
This was a pretty tedious adventure. I may have missed some corner cases
and also restructured a bunch of seemingly unrelated stuff that was
necessary to respect buck module boundaries.
