SurfaceView: Synchronize all surface view changes with VRI draw

Re landing with the following changes:
We initially cloned the SurfaceControl handle to avoid locking when
accessing the SurfaceControl from the position listener callbacks
running from RT workers. But this meant the last reference to the
layer handle would only be released by GC. If SurfaceViews are
created and destroyed rapidly, we would be at the mercy of GC to
release buffers.

Original change:

There are three transaction queues that can submit SurfaceView
changes.

1. Buffer updates via BBQ apply token
2. SCC apply token
3. ViewRootImpl BBQ apply token

It makes sense for most SurfaceView changes to be synchronized with
ViewRootImpl draws since the caller can optionally synchronize the
change with main window content.

This change eliminates the tmp transaction that is applied directly
via the SCC apply token and instead applies them with the ViewRootImpl
draw transaction.

Also take the opportunity to scope down mSurfaceControlLock usage.
