Disable headlock when in VR videos

VR videos are meant for users to be immersed in the whole space around them. Because headlocks locks users in the front of them, it needs to be disabled in VR videos. If users enabled headlock before entering VR videos, we disable it when VR videos show and reenable it when they are exited.

Fixes Igalia#1698
