Fix various issues with scrolling
This change fixes three issues with scrolling:
- In order for scrolls from script to properly scroll nodes in WebRender that might require a layout, Servo should first flush layout and send the display list to WebRender.
- `overflow: scroll` elements were not scrollable from script. This change also refactors the detection of a potentially scrollable body in quirks mode in order to make it match the specification more closely.
- Enable script scrolls in Layout 2020 by adding an implementation of the scroll area query, which is necessary to ensure that an element does support scrolling.
Each of these changes is a separate commit here with corresponding test expectation updates.
Fixes#29659.

Script will only scroll if it detects that an element has a scrolling
box, so this change adds an implementation of the scroll area query to
Layout 2020. This allows some scrolling tests to start passing.
This change also updates all expected results in css-backgrounds and
cssom-view.
Before the code was only allowing `overflow: hidden` elements to scroll.
This fixes that issue and also clean up the code that deals with
detecting whether the body is a "potentially scrollable" in quirks mode.
Scrolling from script should flow layout and send a display list to
WebRender. This allows all of the scroll nodes to exist in WebRender
before asking it to move the node.
See https://gist.github.com/paulirish/5d52fb081b3570c81e3a.
Fixes#29659.
sslfail.html and websocket_disconnect.html are already expected to fail
in layout-2013.
text-indent-percentage-001.xht and text-indent-tab-positions-001.html
fail in layout-2020 due to lack of support for text-indent and tabs.
Fix checking for empty set in getElementsByClassName
Because empty set with `.all(predicate)` will always return `true`, it will result in always filtering wrong elements when the classes is empty set.
Thus, we return earlier with `always_empty` HTMLCollection in the empty classes case so that we can avoid filtering on empty sets.
With adding the checking, we can fix the failures in `/dom/nodes/getElementsByClassName-empty-set.html`.

This change moves all of Servo's WPT Python support scripts into one
directory as they were previously scattered throughout the directory
structure. This should allow more code reuse and make it easier to
understand how everything fits together.
The changes:
- `tests/wpt/update` → `python/wpt/importer`
- `etc/ci/upstream-wpt-changes/wptupstreamer` → `python/wpt/exporter`
- `etc/ci/upstream-wpt-changes/test.py` → `python/wpt/test.py`
- `etc/ci/upstream-wpt-changes/tests` → `python/wpt/tests`
- `tests/wpt/servowpt.py` →
- `python/wpt/update.py`
- `python/wpt/run.py`
- `tests/wpt/manifestupdate.py` → `python/wpt/manifestupdate.py`
This change also removes
- The ability to run the `update-wpt` and `test-wpt` commands without
using `mach`. These didn't work very well, because it was difficult
to get all of the wptrunner and mach dependencies installed outside
of the Python virtualenv. It's simpler if they are always run through
`mach`.
- The old WPT change upstreaming script that was no longer used.
Fix calculation of block axis for abspos elements in Layout 2020
The calculation of the block axis positioning of absolutely positioned elements was using the inline size of the containing block instead of the block size.

elements was using the inline size of the containing block instead of
the block size.
Also organize some of the imports. Now that Servo only uses Python 3,
this module is unnecessary. This is part of the gradual migration to
using only Python 3.
Have all mach command accept "--with-layout-2020" and "--layout-2020"
Some command accepted one and some the other. This changes makes them all accept both so it's no longer necessary to remember which uses which.

This also removes imported position: sticky tests from the Mozilla
directory. These were only supposed to be temporary until the upstream
version from WPT were imported.
This change adds support for the <iframe> element to Layout 2020. In
addition, certain aspects of the implementation are made the same
between both layout systems.
Add an implementation of `URL.canParse` as a static method. See
