Tonemap everywhere in PixelCopy

* Hookup tonemap support for PixelCopying a SurfaceView
* Fix issue in PixelCopying a SurfaceView where the wrong dataspace was
  retrieved from the last queued buffer, since the bufferqueue dataspace
  may drift due to another process like camera setting the dataspace
  without being propagated to the app process
* Cleanup LayerDrawable to share code
