Disable VR compatibility display

The VR compatibility display is causing issues with the 2d <--> VR
transition in SurfaceFlinger. Disable it until we figure out what's
going on.

Bug: 34280358

Test: Had flakiness when transitioning into/out of VR mode via cube sea
and treasure hunt, with the VR compatibility display enabled. After
disabling the VR compatibility display, transitioning was much more
stable, though not perfect.
