HWC2: Add properties to revert latching changes
Adds two properties:
debug.sf.latch_unsignaled - This causes SurfaceFlinger to latch
buffers even if their fences haven't signaled
debug.sf.disable_backpressure - This causes SurfaceFlinger to skip
propagating backpressure back to apps by not running when it
detects that a prior composition missed hardware vsync
