Move GPU interfaces off of Service Manager
This changes the GPU process to expose browser-facing interfaces through
the Content ChildProcess interface.
ChildThreadImpl now allows subclasses to provide a BinderMap to handle
incoming interface binding requests from the browser. This is a fairly
simple drop-in replacement for what used to be done through
the Service Manager with a ConnectionFilter.
There should be no behavioral changes here. In particular for
GPU interfaces, this CL is careful to preserve the behavior which avoids
binding incoming interface receivers until |OnGpuServiceConnection()| is
invoked.
