Since #29950, unit tests were only running with the legacy layout, and
there was no way to run them for layout 2020.
This patch makes './mach test-unit' run unit tests for both.
Also doing some changes so that the layout 2020 floats.rs tests compile.
Do not do the duplicate workflow checks for main workflow jobs triggered
by 'issue_comment' GitHub Actions. This prevents try jobs from being
skipped. This issue was not detected in my testing, because the main
workflow does not run in personal repositories and 'issue_comment'
actions cannot be tested from PRs.
This is the last piece of the puzzle to turning off bors. This makes
functionality provided by bors to understand "@bors-servo try" a GitHub
Action. For now the syntax is more or less the same, but we can modify
it in the future and even add support for custom configuration options
(more specific build combinations or even passing compiler flags).
The big difference between this and what bors does is that there is no
merge commit. GitHub simply runs tests on the version of the branch that
is on a pull request. There is always the risk that tests might start
failing when a branch is rebased, but this offers a bit more control
because you can easily rebase from the PR and the merge queue will check
this as well.
* compositing: rename WindowEvent to EmbedderEvent

* winit: rustdoc link to EmbedderEvent
* winit: use new name queue_embedder_events_for_winit_event
* Add initial support for css-text-3 whitespace handling
This adds initial support for whitespace handling from the CSS
specification for Layout 2020. In general, the basics are covered. Since
test output is very sensitive to whitespace handling, this change
incorporates several fixes:
1. Whitespace is collapsed according to the Phase 1 rules of the
specification, though language-specific unbreaking rules are not
handled properly yet.
2. Whitespace is mostly trimmed and positioned according to the Phase 2
rules, but full support for removing whitespace at the end of lines
is pending on a temporary data structure to hold lines under
construction.
3. Completely empty box fragments left over immediately after line
breaks are now trimmed from the fragment tree.
4. This change tries to detect when an inline formatting context
collapses through.
Fixes#29994.

A block that establishes an independent formatting context is placed
next to previous floats, so we should add their sizes when computing
the intrinsic contribution of the parent block container.
Remove rayon_croissant and refactor the way that information about
floats in flows bubbles up. This simplifies the code a good deal and
lets us take advantage of some more optimized functions provided by
rayon. This removes 2 crates from the dependency tree.
In addition, this allows avoiding passing `contains_floats` up from
every box tree construction function. This makes things simpler, but
also opens up the possibility of passing more of these flags up in the
future (such as `contains_counters`).
calculate_inline_content_size_for_block_level_boxes was relying on
inline_content_sizes to get the size of each block-level box child.
For absolutely positioned boxes, this was 0x0.
That was no-op before #29887, but then it prevented adding the sizes
of a sequence of floats. Abspos should just be ignored instead of
treated as 0x0.
This patch removes inline_content_sizes, moves the logic into
calculate_inline_content_size_for_block_level_boxes (the only caller),
and handles abspos correctly.
* Place replaced and non-auto inline size independent FCs next to floats
The CSS2 specification says that replaced content and independent
formatting contexts should be placed next to floats. This change adds
support for that, but punts on support for independent formatting
contexts that have an auto inline size. With an auto inline size, we
which requires a much more complex layout algorithm.

Much of the code used to import WPT tests from upstream has been moved
to the WPT repository itself, so this can be reused. In addition,
simplify the workflows by merging the entire process into mach and also
directly into the GitHub workflow. This should fix WPT imports after
combining compilation of layout and legacy layout.

This API has been removed in the latest version of WebRender and we can
simply get this information from the compositor-side scroll tree. In
addition, this change limits the amount of data sent to the pipeline
that actually changed and gives the function in the compositor a better
name.

Use the WebRender clip chain API
The old clipping API has been removed from WebRender, so this switches
both legacy and new layout over to use the clip chain API in preparation
for the WebRender upgrade.

Make Layout 2020/2013 a runtime switch
This change makes the choice between Layout 2020 and Layout
2013 a runtime switch. The main part of the patch is removing all layout
related compile-time flags from the style crate. This makes the style crate a
lot simpler, but now Layout 2020 parses a good deal of features that it doesn't
support (table, vertical-align, etc). The good news is that we plan to add
these features to Layout 2020.
- Compile a single style for both Layout 2020 and Layout 2013
- Remove layout_2020/layout_2013 features
- Update GitHub workflows for single compilation
- Update test results
