Eric Rozell 59105f6b1e Adds hook for platform-specific View props
Summary:
Platforms that plug in to react-native may require additional props that are specific to those platforms. For example, already in react-native there are props that are specific to Android (`accessibilityComponentType`, `needsOffscreenAlphaCompositing`, etc.), props that are specific to iOS (`accessibilityTraits`, `shouldRasterizeIOS`, etc.) and props that are specific to tvOS (`isTVSelectable`, `tvParallaxProperties`, etc.).

I need to add properties to `react-native-windows`, and I'd prefer not to override the entire `ViewPropTypes` file as it is a risk that things in react-native-windows fall out of sync with react-native.

Fixes #15173
