Up until now, Servo was using a very old version of time to get a
cross-process monotonic timestamp (using `time::precise_time_ns()`).
This change replaces the usage of old time with a new serializable
monotonic time called `CrossProcessInstant` and uses it where `u64`
timestamps were stored before. The standard library doesn't provide this
functionality because it isn't something you can do reliably on all
platforms. The idea is that we do our best and then fall back
gracefully.
This is a big change, because Servo was using `u64` timestamps all over
the place some as raw values taken from `time::precise_time_ns()` and
some as relative offsets from the "navigation start," which is a concept
similar to DOM's `timeOrigin` (but not exactly the same). It's very
difficult to fix this situation without fixing it everywhere as the
`Instant` concept is supposed to be opaque. The good thing is that this
change clears up all ambiguity when passing times as a `time::Duration`
is unit agnostic and a `CrossProcessInstant` represents an absolute
moment in time.
The `time` version of `Duration` is used because it can both be negative
and is also serializable.
Good things:
- No need too pass around `time` and `time_precise` any longer.
`CrossProcessInstant` is also precise and monotonic.
- The distinction between a time that is unset or at `0` (at some kind
of timer epoch) is now gone.
There still a lot of work to do to clean up timing, but this is the
first step. In general, I've tried to preserve existing behavior, even
when not spec compliant, as much as possible. I plan to submit followup
PRs fixing some of the issues I've noticed.

`webxr` depends on a very old verison of `time`, which allowed serializing
monotonic clock output. This isn't possible on all platforms, so newer
versions of `time` do not allow this. In order to stop using the old
0.1 versions of `time` we have to stop relying on times passed from `webxr`
to Servo. This change does that, at the cost of removing the XR
profiling feature. It has to be rewritten in another way in the `webxr`
crate.

As seems #31500 still remain opened here's the next partial fix.
Fixed list: `unused_mut`, `clippy::needless_borrow`,
`clippy::match_ref_pats`, `clippy::borrow_deref_ref`, `clippy::ptr_eq`,
`clippy::unnecessary_cast`, `clippy::derivable_impls`,
`clippy::collapsible_match`, `clippy::extra_unused_lifetimes`,
`clippy::map_clone`, `clippy::manual_filter`.
- [x] `./mach build -d` does not report any errors
- [x] `./mach test-tidy` does not report any errors
- [x] These changes are part of #31500.
- [x] These changes do not require tests because are only cosmetic.

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.
---
<!-- Thank you for contributing to Servo! Please replace each `[ ]` by `[X]` when the step is complete, and replace `___` with appropriate data: -->
- [x] `./mach build -d` does not report any errors
- [x] `./mach test-tidy` does not report any errors
- [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. -->
