BBQSurface: Give client a chance to observe transform hint earlier
The client may be observing the transform hint through the Surface.cpp
codepath however Surface#mTransformHint will only be updated on
queueBuffer. However imagine a scenario like this:
1. transform hint changes on server
2. queue buffer
2. repeat queue buffer
3. callback for queue buffer 1 and 2, updates transform hint on
client
4. queue buffer 4
5. Client now observes transform hint
6. Queue buffer 5(!) will finally contain the transform hint.
With this change we give the client a chance to observe the tranform
hint in this scenario before queue buffer 4. In the case of the
ScreenDecorOverlay's which rarely redraw, this seems to fix some
persistent pre-rotation issues.
Bug: 184842607
Test: Existing tests pass.
