Shut-down of the background hang monitor(bhm) is currently problematic:
- it does not always run until the monitored script-thread does(see
"BackgroundHangMonitor has gone away" mentioned in
https://github.com/servo/servo/issues/34158).
- it shuts-down before the constellation(good, so actually
https://github.com/servo/servo/issues/24850 was "fixed" but in a way
that introduced a new problem), but using a mechanism that allows it to
shutdown before script(the problem above).
- there are various mechanism(see the doc comments removed by this PR)
in place which are meant to ensure a clean shutdown despite the above
problems; those are complicated, and become unnecessary once those
problems are fixed.
All of the above is fixed by the changes in this PR, which ensure the
bhm does not shut-down before script, and also maintains the invariant
that it must shut-down before the constellation(in single-process mode)
or before the main thread(in multi-process mode), but using a mechanism
which allows it to keep running until script shuts-down.
An unnecessary option around the exit signal is also removed.
As a positive side-effect, it also ensures that any script-thread is
shut-down before the constellation(because for the bhm worker to exit,
the monitored script must have exited first), so this should also fix a
host of other problems noted in
https://github.com/servo/servo/issues/30849, but each should be
confirmed independently(and various other improvements seem possible in
their specific contexts, such as joining on script threads, and removing
the `ScriptThreadMessage::ExitScriptThread`).
Fixes: https://github.com/servo/servo/issues/24850 and part of
https://github.com/servo/servo/issues/34158
Testing: Unit tests in `component/background_hang_monitor/tests`. Also

For current implementation, when a command may trigger a navigation,
webdriver only waits for document readiness state.
However, not all navigations make change in document.
This PR handles more cases for waiting for a navigation, and apply to
`element_click`.
- Before sending a command which may trigger a navigation, `webdriver`
sets `load status send` to `embedder`, `constelltation` and `script
thread` to listen to `navigation events`.
- Webdriver check if there is a navigation with `script thread`.
- If the navigation is loading a new url, webdriver checks if the
request is approved with `constellation`, then waits for document
readiness state.
- If the navigation is a hashchange, webdriver waits untill all new
generated dom events have been processed.

vello_cpu does not have any tests timeouts, because we do not need
download stuff from GPU as all work happens on CPU. So performance wise
it's better then classic vello at least for our usecase. There are some
vello bugs, but I think we will be able to sort them out within
upstream, eventually. Interestingly enough there are no new PASS like
they were with classic vello.
Difference with raqote can be observed here:

Add vello backend by implementing Backend traits in canvas crate (so
this lives in canvas_paint_thread - embedded process). Current
implementation uses normal wgpu, so we block on GPU work. Vello backend
is gated behind `vello` feature and `dom_canvas_vello_enabled` pref.
Feature-wise this backend is on on par with raqote (sometimes better
sometimes worse), but performance wise it's worse.
## Known vello problems:
- image roundtrip does not work (fixed in

- `/html/canvas/element/path-objects/2d.path.rect.selfintersect.html`
- There is currently no way to do put image properly in vello as we
would need to ignore all clips and other stuff (we try to work around
this on best effort basis)

- precision problems
- `/html/canvas/element/path-objects/2d.path.stroke.scale2.html`
- `/html/canvas/element/path-objects/2d.path.arc.scale.1.html`
## Known servo problems
- bad performance due to blocking on GPU work
- some get/put intensive tests `TIMEOUT`
- proper shadow support (non-blocker as we already are living without it
now)
- support for rect shadow is there but unimplemented currently as that's
the state in raqote
Testing: `mach try vello` will run normal WPT (with raqote) +

Previously, the Constellation would immediately ask the Compositor to
shut down a pipeline, even before the ScriptThread finished shutting it
down. This meant that the Compositor might remove a Pipeline and then
re-add it if the ScriptThread sent a Pipeline-related message (such as a
new display list) in the meantime.
This change makes it so that the Compositor waits for both the
Constellation and the ScriptThread to finish shutting down a Pipeline
before removing its data. In addition, the Constellation no longer
synchronously waits on the Compositor when shutting down Pipelines. This
was important when the Compositor would talk to the ScriptThread
directly, but isn't necessary any longer.
Testing: This is very hard to test, because it depends on the creation
and destruction of many iframes and the particular timing of of all
the messaging between Servo bits. That said, this was tested manually
by observing the completion of Speedometer 2.1.

There are currently five places that scroll offsets are stored:
- DOM: A set of scroll offsets used for script.
- Layout: An array of scroll offsets that is used for tracking
layout-side scroll offsets.
- Layout: The scroll offsets stored in the `ScrollTree`. These are
currently unset and unused.
- Compositor: The scroll offsets stored in the `ScrollTree` mirrored
from layout.
- WebRender: The scrolled offsets stored in the WebRender spatial tree.
This change is the first step in combining the first three into the
layout `ScrollTree`. It eliminates the extra array of scroll offsets
stored in layout in favor of the storing them in the `ScrollTree`. A
followup change will eliminate the ones stored in the DOM.
- In addition the `ScrollState` data structure is eliminated as these
are
now stored in a `HashMap` everywhere when passing them via IPC.
- The offsests stored in layout can now never scroll past the boundaries
of the scrolled content.
