Summary:
Previously, ViewPropsMapBuffer conversions were hardcoded deep in Android infrastructrue. I've generalized this into a different mechanism to allow any Props struct to support MapBuffer props.
There are still some things that need to be cleaned up and this should be treated as experimental. One thing we likely want to do is remove the hardcoded IDs (fine for codegen'd code; less so for handwritten) and use compile-time-hashed IDs instead with human-readable string names.
