This remotes the APZInputBridge interface over the PAPZInputBridge
protocol in the case of the GPU process, and makes the GPU process'
main thread act as the APZ controller thread in that process. If
there is no GPU process we continue as before and the APZInputBridge
interface implementation is the concrete APZCTreeManager instance
in the UI process.
The main changes in this patch are moving all the code associated with
these messages out of APZCTreeManager{Parent,Child} and into
APZInputBridge{Parent,Child}. APZCTreeManagerChild now returns an
APZInputBridgeChild instance via InputBridge(), instead of returning
itself. The SetControllerThread call in the GPU process is also updated.
