Allow out of tree platforms to customize cursor values (facebook#44841)

Summary:
Pull Request resolved: facebook#44841

Out of tree platforms like react-native-macos and react-native-windows may wish to support different cursor types than are currently supported in mobile React Native (currently only "auto" and "pointer").

Since the Cursor is applied on the BaseViewProps across all platforms, we need an extension point where a platform can inject it's own header for defining a cursor. This header will also have to include it's own implementation of `fromRawValue` to parse the cursor value from RawProps into the host platform implementation of Cursor.
