ui: Improve instantiation of AsyncPixelTransferDelegate classes.

Add proper platform abstraction for async pixel transfer interface
by moving android implementation into _egl.cc, current stub
implementation into _sync.cc and add platform specific files
that decide what implementation to use.

BUG=187886
