Add annotation processor for @ReactProp

Browse Source 
Summary:
The annotation processor finds subclasses of ViewManager and ShadowNode and generates classes that can both provide a mapping of property names to their type as well as a way of setting these properties.

This avoids having to do reflection to find the properties.

The annotation processor is currently not working when building with Gradle.
