Update teleport to use four separate reference spaces

Since reference spaces are only valid for a given session, the
non-immersive (magic window or identity) and immersive reference
spaces need to be saved separately. We also need to separately
store and use offset reference spaces, and recalculate them
from the appropriate base un-offset reference space as needed.
