…onnected., a=testonly

Automatic update from web-platform-tests
End XRSession when data provider is disconnected.

There are slightly different code paths to handle the disconnect for
immersive and non-immersive sessions. There can only be one immersive
session, but there can be multiple non-immersive sessions and they all
use the same magic window provider as their data provider.
