Summary:
Provides an alternative way of diffing props on Android side. Instead of passing dynamic JSON values from JS, the new approach diff C++ props and serializes difference into a `MapBuffer`. Current implementation does this only for `RCTView` component to test performance, correctness and memory impact (as MapBuffers are supposed to be more compact and performant).
This way of passing props allows for additional alignment between platforms, as C++ props are now source of truth for the view state, similar to iOS. At the same time, changing serialization method requires reimplementing `ViewManager` codegen (done manually for now) to account for `MapBuffer`s.
Changelog: [Added][Android] - Added an experimental prop serialization path based on MapBuffer
