Fix wallpaper scaling issues

Browse Source 
BlastBufferQueue adapter will modify the passed in SurfaceControl
properties. This conflicts with updates from the Wallpaper service. To
fix this, create a wrapper layer for the wallpaper BlastBufferQueue.

Fixes: 185561343
Test: rotate wallpaper, confirm wallpaper is scaled correctly
