Modify SurfaceView to use SurfaceFlinger child surfaces.

Here we have SurfaceView bypass the WindowManager and speak
directly to SurfaceFlinger using child surfaces. We also
implement some logic in the WM to handle child surfaces
in various Surface replacement scenarios.

For those following along in the revert Saga, this
also includes the follow up CLs to the original CL.
- Surface inset calculation
- Animation fixes.

The error causing revert was a deferTransactionUntil(-1)...-1
cast to uint, defer transaction until MAX_UINT.

Test: Existing tests still pass (except for the ones that don't and will be deleted).
