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.

When the decision job decides that a workflow should be skipped because
an identical one has already run, that workflow should be marked as
successful and not unsuccessful.

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.

Including hit tests in non-hit test display list items is no longer
supported in upstream WebRender, so this change switches legacy layout
to always use explicit hit test display list items.

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

Collect android build setup into two methods
This is small refactor which tries to isolate all of the Android setup
into a couple methods, so that it is easier to reason about in the
scripts. This doesn't change any behavior but does fix a few small
linting errors in the existing code.
Note: The Android build is currently broken and this change doesn't fix
it. It shouldn't break it any more though.

Vendor the current version of WebRender
This is a step toward upgrading WebRender, which will be upgraded and
patched in the `third_party` directory. This change vendors the current
private branch of WebRender that we use and adds a `patches` directory
which tracks the changes on top of the upstream WebRender commit
described by third_party/webrender/patches/head.

Split layout_in_flow_non_replaced_block_level
This function is already quite big and the changes necessary for
properly laying out independent formatting contexts next to floats will
make it even more unwieldy. Split the function in two and add a helper
for calculating the containing block for children and the margin. As
time goes on the independent formatting case is probably going to be
more like the replaced case anyway.

Layout 2020: Optimize collapsible margin lookahead
Every time that we would lay out a block box that could collapse its top margin with its contents, we would do a lookahead to compute the resulting margin in order to place floats correctly.
The problem is that this lookahead could iterate several descendants, but then when laying these we would run the lookahead again.
This patch restricts the lookahead to boxes that either aren't collapsing their top margin with their parent, or that have 'clear' different than 'none' (since clearance prevents collapsing margins with the parent).
Since the lookahead stops iterating when it finds a box that doesn't collapse its top margin with its parent, or whose 'clear' isn't 'none', this should ensure that lookahead never handles the same box twice.
