This implements the rest of the bulk of float support. Now inline
element flow around floats and floats can be pushed down by inline
elements before them.

PlacementAmongFloats was assuming that there would always be a FloatBand
at a position smaller than or equal to the given ceiling, but this was
not the case for negative ceilings.
The reason is that the FloatContext initialized the FloatBandTree with
a band at 0, and another at +∞.
This patch changes the initial bands to −∞ and +∞. This seems more
consistent and matches the expectation of PlacementAmongFloats.
`OnceCell` is now part of the standard library and we'll be able to use
it once we upgrade rust. For now we can use the version that's shipped
behind a feature flag in rust. This removes a dependency on one crate.
Now that our dependencies are using a newer version of rand we can
upgrade. This change also disables the WebRender debugger feature
because it has been removed in later versions of WebRender and allows
deduplicated the rand dependency as well as quite a few others.
When layout was split into two phases, floats were laid out as direct
children of the inline formatting context. This meant that they were
positioned properly, but not properly made children of their inline
ancestors' stacking contexts. This change maintains the proper
positioning of floats, but positions them relatively to their inline
ancestors.
The big change here is that `text-align` needs to be taken into account
before actually laying out LineItems. This has the added benefit of
setting inline layout for the implementation of `text-align: full`. Now
all line items are laid out at the real final position and we can adjust
the `start_corner` property of float `BoxFragments` when their ancestors
are laid out.

* Fix `mach test-wpt` to make crash tests work
There are two issues related to crash tests:
1. test-wpt is unable to find existing crash tests even when
called with --test-types=crashtests. The fix here is to
add crashtests to the default test suite types to python/wpt/run.py
2. When running in headless mode, crashes in style threads
don't cause servo to crash because the logic in constellation.rs
currently calls handle_panic only when the top-level browsing
context id is some value. Since style pool threads are shared,
they always generate Panic messages with None as top-level
browsing context id.

* Send bactrace to stderr and capture it in test runner
Servo's panic hook writes backtraces to stdout. This
patch changes it so they are written to stderr.
The crash test executor for servo in WPT grouping formatter
was also not capturing the output correctly for crashtests
as the log events were being aggregated based on thread name
which doesn't seem to match correctly in case of crashtests.
This patch also fixes the log grouping logic to be based on
test name.

The problem is a double-borrow of the `when_defined` member. The fix is
to let go of the borrow before resolving the promise which will
eventually try to borrow `when_defined` again.
Fixes#30120.
This reuses our existing undisplayed style generation, but in a
per-document rather than per-nsComputedDOMStyle object, which means that
we can avoid re-resolving styles of elements in display: none subtrees
much more often.
This brings the test-case in the bug to par with other browsers or
better, and is much simpler than the initial approach I tried back in
the day.

Provide container information in computed::Context and use it to resolve
the container queries.
This still fails a lot of tests because we are not ensuring that layout
is up-to-date when we style the container descendants, but that's
expected.

After bug 1768278 and bug 1767815 there's no more uses of the cliprounded value
in the tree (also it causes artifacts on HiDPI screens so we probably don't
want new usages).
The "sheet" value is unused, and the other values other than "default" and
"none" are only derived from "default", so they don't need to be exposed in the
style system.
