Don't report test results for closed PRs
When doing a try run, bors will often push the last closed merge onto the branch before pushing the change to try. This means that test results get reported on closed PRs. There are two issues with this:
1. Doing too much work on the bots.
2. Extra results on closed PRs.
This changes fixes the second issue.
Fixes#29583.

eca0acf459 uncovered a bug in the way that
the scrolling area of `window` was calculated and broke scrolling on the
root element. This change does two things in order to fix that:
1. Does a partial revert of eca0acf459 in
order to get scrolling from script working again on the window
object.
2. Has the compositor always generate a frame for scrolls starting from
script and waits for them. This is speculative fix for flakiness in
root scrolling tests on CI.

Fix an assertion failure in Layout 2020
The recent changes to containing blocks, exposed an issue in the StyleExt trait:
- When deciding whether an element creates a reference frame, whether or not it is a non-replaced inline is taken into account when determining if it has a transform.
- When deciding whether an element creates a stacking context for all descendants, whether or not it is a non-replaced inline is *not* taken into account when determining if it has a transform.
In both cases, elements that are inline should not be considered to have transforms. This commit fixes that issue as well as making it so that inlines cannot be transformed. Note that is also breaks transforms on replaced elements, but that functionality was fairly half-baked due to the inconsistent determination of transforms.

Detect body elements during layout
During layout it is often useful, for various specification reasons, to know if an element is the `<body>` element of an `<html>` element root. There are a couple places where a brittle heuristic is used to detect `<body>` elements. This information is going to be even more important to properly handle `<html>` elements that inherit their overflow property from their `<body>` children.
Implementing this properly requires updating the DOM wrapper interface. This check does reach up to the parent of thread-safe nodes, but this is essentially the same kind of operation that `parent_style()` does, so is ostensibly safe.
This change should not change any behavior and is just a preparation step for properly handle `<body>` overflow.

Move `FromScriptLogger` and `FromCompositorLogger` to seperate file
<!-- Please describe your changes on the following line: -->
This PR is an attempt to refactor the `constellation.rs` file in order to make it more readable. Starting the initiative with moving `FromScriptLogger` and `FromCompositorLogger` to a separate`logger.rs` file as they don't have any major dependency to be in the `constellation.rs` file itself.
Also noticed a broken link in `docs/HACKING_QUICKSTART.md` file. Adding the correct url.

Rework CB management during stacking context tree construction
Manage containing blocks and WebRender `SpaceAndClip` during stacking context tree construction using the `ContainingBlockInfo` data structure. This will allow us to reuse this data structure whenever we traverse the fragment tree. In addition, `StackingContextBuilder` is no longer necessary at all. This change also fixes some bugs where fixed position fragments were not placed in the correct spatial node. Unfortunately, these fixes are difficult to test because of #29659.

Constellation seems to have lots of code that could be moved into
seperate files. `FromScriptLogger` and `FromCompositorLogger` seem
to qualify for that.
Moved FromScriptLogger and FromScriptLogger to logger file.
Implement outlines in layout-2020
<!-- Please describe your changes on the following line: -->
This only covers the CSS2 properties: 'outline-width', 'outline-style',
'outline-color', and the shorthand 'outline'.
CSS UI 3 introduced 'outline-offset', which is left for a follow-up.
'outline-color: invert' isn't included either, but note CSS UI says that
conformant UAs may ignore the 'invert' value on platforms that do not
support color inversion of the pixels on the screen.

Fix flakiness in animation tests
1. When updating the animation timeline, ensure that nodes that are
animating are marked dirty, if necessary, so any style queries will
force a layout flush.
2. Disable the problematic transition test suites, as they are in Gecko.
These suites often fail when Servo is so overloaded that it cannot
deliver frames fast enough to get more than two samples during the
animation lifecycle.
Fixes#28334.
Fixes#26435.
Fixes#21486.

Normalize corner radii that add up to > 100%
WebRender already seems to be doing this normalization, but this is needed by inner_radii in order to properly compute the reduced radii when background-clip is content-box or padding-box.
This will also be needed for expanding the radii for box-shadow or outline.

Reset to in-memory stream with empty byte sequence for None init body
Because the response body stream is initialized with FetchResponse, it cannot be processed with in-memory empty sequence. Thus, instead of using the FetchResponse stream, we'll reset it to Memory body stream with empty byte sequence if there's no init body.
With this PR, we can fix the TIMEOUT in `/fetch/content-type/response.window.html` so I think it should fix#22304.

Round text decoration thickness to >= 1 device pixels
Previously the thickness coming from font metrics could be something like 0.7px, so with 1dppx it would be painted as either 1 or 0 device pixels.
Enforcing at least 1 device pixel ensures that the decoration will be visible, and rounding to an integral amount of device pixels ensures that the thickness won't vary depending on the position.
The specification requires this behavior when text-decoration-thickness is set to a length or percentage. It's not clear if it should also happen by default, but this seems to match other browsers (except for WebKit rounding up instead of to the nearest integer).
The test text-decoration-thickness-from-zero-sized-font.html is now failing because of #29675.

Previously the thickness coming from font metrics could be something
like 0.7px, so with 1dppx it would be painted as either 1 or 0 device
pixels.
Enforcing at least 1 device pixel ensures that the decoration will be
visible, and rounding to an integral amount of device pixels ensures
that the thickness won't vary depending on the position.
The specification requires this behavior when text-decoration-thickness
is set to a length or percentage. It's not clear if it should also
happen by default, but this seems to match other browsers (except for
WebKit rounding up instead of to the nearest integer).
The test text-decoration-thickness-from-zero-sized-font.html is now
failing because of #29675.
Make WPT results output more useful
Before when a subtest failed, the text of the failed assertion was not printed. This changes makes sure that it is printed in both the console and the aggregated test output.
Also fix a couple typing errors.

Fixes for running WPT tests in GitHub Actions
- [report aggregated WPT results based on layout](5ad1f241e2)
- [Run wpt only on try-wpt,try-wpt-2020 branches](0b30baf9a4) fixes a bug introduced in #29662
Because the response body stream is initialized with FetchResponse, it
cannot be processed with in-memory empty sequence. Thus, instead of
using the FetchResponse stream, we'll reset it to Memory body stream
with empty byte sequence if there's no init body.
Update layout-2020 test expectations
Some tests are now passing thanks to #29661.
