Dirty canvas when exiting immersive sessions
Fixes https://github.com/servo/servo/issues/26162, fixesservo/webxr#155
We basically end up in a situation where the main thread is asleep. It's unclear to me why it doesn't wake up after attempts to interact with the screen, but we stopped dirtying the canvas during the immersive session (https://github.com/servo/servo/pull/26077) so the main thread wasn't awake initially.
This is probably not the cleanest fix -- we really should not be ending up in situations where the main thread is perma-asleep -- however, we should be dirtying the canvas after exiting immersive mode _anyway_ since the contents need to be shown to the user, so this fix is still valid, even if it's not fixing the root cause.
refactor: rename XR to XRSystem
<!-- Please describe your changes on the following line: -->
This PR renames XR to XRSystem.

- [X] These changes fix#25732
<!-- Either: -->
- [ ] There are tests for these changes OR
- [X] These changes do not require tests because it's the changing of a name (XR -> XRSystem)
<!-- Also, please make sure that "Allow edits from maintainers" checkbox is checked, so that we can help you if you get stuck somewhere along the way.-->
<!-- Pull requests that do not address these steps are welcome, but they will require additional verification as part of the review process. -->
