Remove startEmptySurface from SurfaceManager (#48479)

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/48479

[Changelog] [Internal] - Remove startEmptySurface from SurfaceManager

Most of the logic deleted here does not seem to be needed as the core functionality is in:

https://github.com/facebook/react-native/blob/main/packages/react-native/ReactCommon/react/renderer/scheduler/SurfaceHandler.cpp#L88-L96

And this code path can be reached both via
- `startSurface` (by passing in an empty `moduleModule` OR
- `startEmptySurface`
