DO NOT MERGE SF: Add property to disable HWC virtual displays

Adds the property debug.sf.disable_hwc_vds, which will disable the use
of Hardware Composer virtual displays inside SurfaceFlinger (falling
back to SurfaceFlinger management and client composition of such
displays).

Also adds a Binder debug interface for controlling this behavior.
