This is an implementation for `scrollIntoView`. For now, it is called
when a certain element gains focus.

The recent changes that cached the Scroll Tree present an opportunity to
calculate the queries that consider transform and scroll (dubbed as post
composite queries) accurately.
This PR propose a solution for this calculation by noting the lowest
scroll tree nodes that would affect a fragment. To do this, each
fragment would store a new attribute `spatial_tree_node` -- scroll tree
node id that we could use for the query. This referencing is considered
because the scroll tree node construction is managed by the fragment
itself. Therefore it would ease the managing the possibly stale
reference and future query cache invalidation considering the
development of incremental layout.
The bounding box query then could transform the bounding content rect of
a fragment using the computed current transformation matrix.

The compositor was accepting scroll offsets from the ScriptThread
without checking their boundaries. In some cases this could cause a
temporary discrepancy with the rendered scroll offset. This change makes
it so that all offset updates for scroll ayers in the compositor do not
scroll past the scroll boundaries of the node.
Testing: Two new tests pass with this change:

Add a skeleton implementation of FontFaceSet interface with support
for resolving the `document.fonts.ready` Promise when the loading of
web fonts is completed.
This change exposes new failures in the web platform tests.
These were ERROR before the change because `document.fonts.ready` caused
a `ReferenceError` causing the tests to be aborted and they now FAIL:
- /css/CSS2/linebox/vertical-align-top-bottom-001.html
- /css/css-flexbox/flex-one-sets-flex-basis-to-zero-px.html

- /css/css-text/text-autospace/text-autospace-ligature-001.html
- /css/css-values/calc-size/calc-size-width.tentative.html
These were TIMEOUT before the change because `document.fonts.ready` was
a ReferenceError and the tests were asynchronous (reftest-wait). These now
FAIL because the assertions are now executed after fonts are loaded:

* These two tests only PASS in Layout 2020:
- /css/CSS2/positioning/inline-static-position-001.html
- /css/cssom-view/getBoundingClientRect-empty-inline.html
These two tests have subtests that PASS intermittenttly:
- /fetch/metadata/generated/css-font-face.sub.tentative.html
- /css/css-fonts/generic-family-keywords-001.html
These tests are new TIMEOUTS that used to FAIL because
`documents.fonts.ready` was undefined:
- /resource-timing/TAO-match.html
- /resource-timing/content-type.html
- /resource-timing/nextHopProtocol-is-tao-protected.https.html
The failure in `/resize-observer/change-layout-in-error.html` could be
due to an issue in the ResizeObserver implementation that is now exposed
with this change, but this needs more investigation.

This change adds a very simple implementation of `border-collapse` for
tables. No harmonization or merging is done at all for borders. Instead,
the largest border for every continuous border sets the size. Instead of
merging different border styles, they are squashed to half size -- which
isn't great, but ensures appropriate positioning.

* Add initial support for sticky positioning for non-legacy layout
Many tests still fail for a variety of reasons. One of the primary ones
is that CSSOM currently does not return correct values for elements
positioned by sticky nodes. This requires changes to WebRender to work
properly.
* Fix an assertion failure in the legacy layout sticky code
In legacy layout, anonymous text wrappers were inheriting the `overflow`
and `text-overflow` properties. This results in the creation of extra
clipping for these anonymous wrappers which could clip away floats. We
will likely implement `text-overflow` differently in non-legacy layout.
This change marks all legacy layout pseudo elements as "legacy" and also
adds a new pseudo element for non-legacy layout that does not inherit
`overflow`.
Fixes#30562.

Main frame scrolling after the WebRender upgrade was broken because the
main frame no longer has content size content bounds and quirks mode
leads to a body with zero height.
Fixes#30368.
Refactor the scrolling and scrollable area calculation on the window
object, to make it better match the specification. This has some mild
changes to behavior, but in general things work the same as they did
before. This is mainly preparation for properly handling viewport
propagation of the `overflow` property but seems to fix a few issues as
well.
There is one new failure in Layout 2020 regarding `position: sticky`,
but this isn't a big deal because there is no support for `position:
sticky` in Layout 2020 yet.

* Upgrade vendored version of WebRender
* Patch WebRender: upgrade version of gleam
* Restore hit testing implementation
* Fix WebRender warnings
* Adapt Servo to new WebRender
* Update results
* Add a workaround for #30313
This slightly expands text boundaries in order to take into account the
fact that layout isn't measuring glyph boundaries.
