Move SynchronousCompositorFactoryImpl into separate h/cc files

This is a long overdue clean up to make future changes in this area
saner. Only shuffling code and these cosmetic changes:

Removed unused SynchronousCompositorImpl* argument from
SynchronousCompositorFactoryImpl::CompositorInitializedHardwareDraw
and SynchronousCompositorFactoryImpl::CompositorReleasedHardwareDraw.

Add virtual SynchronousCompositorFactory destructor.
