Create BaseViewProps for platforms to derive (facebook#38549)

Summary:
Pull Request resolved: facebook#38549

Out of tree platforms may need different implementations of ViewProps. In fact, Android does already with props like `needsOffscreenAlphaCompositing` and `focusable`. This diff is not opinionated on whether these props should actually be shared on all platforms. Props like `focusable` may be a good candidate for generalizing to all platforms. However, there will always be a need for one platform to experiment with a new prop while it's not available yet on another, especially when considering out of tree platforms.

This diff moves the existing ViewProps class to BaseViewProps, aliases ViewProps as BaseViewProps for iOS for now, and moves Android-specific view props to it's own header and implementation.

## Changelog:
[General] [Added] - Support additional View props in out of tree platform Fabric implementations
