Remove ReactNative/Flipper Integration (facebook#40935)

Summary:

This is scheduled to land in 0.74, so I'm removed the native integration as this is not needed anymore.
The only thing I left is a stub class to ease the migration out of `ReactNativeFlipper`.

[Android] [Removed] - Remove ReactNative/Flipper Integration
