Add C++ header for default TurboModules and cross-platform reuse (#44361)

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/44361

In order to keep all platforms in sync (Android, iOS, Windows, etc.), it makes sense to consolidate all C++ TurboModules that we want available by default on all platforms to a shared C++ header / implementation.

This moves the duplicated code from Android and iOS to such a shared module provider and updates relevant build specs.
