Kearwood "Kip" Gilbert a9dbddfdba Bug 1407423 - Ensure that any time we have loaded the Oculus runtime libary, we are polling ShouldQuit,r=daoshengmu
- Ensure ovr_GetSessionStatus is polled even when a VR presentation
  is not active.
- When we fail to initialize an Oculus Session or detect VR hardware,
  immediately unload the Oculus Library as we can't poll for ShouldQuit
  without a valid Oculus session.
- When we poll ovr_GetSessionStatus, we are now updating the mounted state
  in VRDisplayInfo::mIsMounted.
- Added prefs to control enumeration throttling and timeout to release
  VR hardware when inactive.
- Some refactoring to make frame loop more understandable and less
  brittle.
- When throttling enumeration, we ensure that all other VR apis
  also throttle enumeration so that they don't pick up the same device
  during throttling.
- Some long functions in VRManager have been broken up and
  had their inner-workings documented in more detail.
