Kearwood Gilbert d0b2b8da65 Bug 1436791 - Implement gfxVRExternal,r=rbarker
- gfxVRExternal Enables other processes to present
  real or simulated VR hardware to Firefox.
- This functionality is disabled by default, under
  dom.vr.external.enabled.
- VRDisplayInfo, VRControllerInfo, and associated
  structs have been restructured to ensure internal
  state is not exposed via shmem interface.
- Some refactoring to convert structs to
  POD types, enabling them to be located
  in shmem and be memcpy'd.
- Work needed before unpreffing marked
  with "TODO" comments.
