Store the source ID in InsetsFrameProvider 

This CL stores the source ID but not the owner, the index, and the type
in InsetsFrameProvider. In this way, we write less info to the parcel.
Also, we won't use the BinderProxy to generate the hash code for the ID,
but will use the Binder object directly. Because the hash code obatined
from the BinderProxy might change.
