Now that Issue 782845 is fixed, the VrCore fake head tracker works properly in Chromium tests. Thus, we should make it possible for tests to have simulated head movement, or lock the head position into a constant pose to improve consistency.
Marking this as an external dependency until the GVR bug that causes bad file descriptor crashes when the VrCore head tracking service is used gets fixed (b/77718627)
