SurfaceFlinger: update orientation via transactions
This change merges the ISurfaceComposer::setOrientation functionality
into ISurfaceComposer::setTransactionState. It enables the window
manager to atomically update both the display orientation and the
position and size of the windows in a single transaction with
SurfaceFlinger.
