Prevent buggy display orientation when exiting vr

The underlying issue is that the viewport settings were being re-set to
(0,0,-1,-1) on every transition to VR. I've instead extracted the vsync
period updates, and only apply those, as that was really all we wanted
out of it.

Bug: 37093920
Test: Compile and run Vr application. The 2d scene is now no longer in
the weird landscape viewport with portrait orientation if the phone is
in landscape when exiting VR mode.
