Sebastian Markbage 8e3ce0ff98 Refactor Attribute Processing (Step 2)
Summary: Move the ViewAttributes and StyleAttributes configuration into the
Components library since they're coupled and change with the
native component configuration.

This also decouples StyleAttributes from the reconciler by adding it
to the ReactViewAttributes.

To do that, I refactored the property diffing to allow for recursive
configurations. Now an attribute configuration can be a nested object,
a custom configuration (diff/process) or true.

The requireNativeComponent path incorrectly gets its attributes set up
on the root validAttributes instead of the nested style object.
So I also have to add the nested form. Effectively these currently allow
these attributes on props or nested.
