The spec is still using `Scroll-linked`, so we exclude the change of WPT tests.
I believe WPT will get updates once the spec doc is renamed.

Move most the event handling stuff to the DOM. I've left nsMenuBarFrame
for now, but I will be removing that in the future.
The basic set up is:
* nsMenuParent becomes XULMenuParentElement (menubar or popup, manages
the current active menu item)
* nsMenuFrame -> XULButtonElements that return true for IsMenu().
Can't use XULMenuElement because of <button type=menu>, which
behaves like a, well, menu.
This makes the a11y events for menus (DOMMenuItem{Active,Inactive}) make
sense (before that we were firing duplicate Inactive events etc, and the
event order was rather suspicious).

We always use the document timeline of the cloned document, and clone the
paused animation with the preserved progress, even if the original
timeline is null.

This change adds support for `content-visibilty: auto` as well as
showing and hiding content based on the relevancy of the content as
defined in the specification. Changes to relevancy are handled by
triggering updates in a set of `content-visibility: auto` frames stored
in PresShell at the appropriate time in the document lifecycle.
Some tests are now failing due to this feature exposing the failures,
but they will be fixed in later changes.
This change is a reland of an earlier version that properly updates
intrinsic sizes and triggers an update of remembered size for the
purposes of contain-intrinsic-size when content relevancy changes.

The Element caller only cares about avoiding a flush and can use the
observable parent layout stuff.
The scrollframe one clearly wants the cross-process version according to
the comment.

This doesn't change behavior, but clarifies a bit the naming to match
the scrollIntoView() API. Also makes the name generic (rather than
Top/Left/etc), since for scrollIntoView we want to make the axes be
logical.
That will be done in bug 1789464 (probably via an extra ScrollFlag).

[Int]CoordTyped no longer inherits Units because otherwise
instances of [Int]IntPointTyped may get one Base subobject because
it inherits Units, and others because of BasePoint's Coord members,
which end up increasing the [Int]CoordTyped's objects size (since
according to the ISO C++ standard, different Base subobject are
required to have different addresses).

Two tweaks:
* Use nsPresContext::Medium to decide whether to start transitions.
This catches both the print emulation and the before/afterprint event
dispatching code too, which is desirable.
* Don't clone transition effects for print docs. This seems to match
other browsers (click "trigger transition", then Ctrl+P in Chromium
for example).
Move our existing css-animations tests to WPT. They were written for
compat with other browsers so we want to know if other browsers behave
differently.

The blur is a regression from bug 1740989, but it's really uncovering a
regression from bug 1729342, sorta. Before that, we used to focus the
inner text field on rebuild via focusInnerTextBox().
One could argue that the focus fixup rule should really deal with this,
but I guess since content can't really unattach shadow DOM, it's less of
a general issue and more of an implementation detail.
The test uncovers another pre-existing issue (switching from date ->
test was also broken, and we left a bogus ElementState::FOCUS state in
the element).

Some anonymous children are important for properly sizing their parents
even when those parents hide content with `content-visibility`. This is
shown by regressions in the proper layout of some form elements with
`content-visibility`.
This change introduces a more conservative approach for avoiding layout
of hidden content. Instead of leaving all children dirty during reflow,
reflow anonymous frames (and nsComboboxDisplayFrame, a specialized kind
of anonymous frame). This change means that frames may only lay out some
of their children, so it must introduce some more changes to assumptions
during line layout.
In addition, this change renames `content-visibility` related methods in
nsIFrame in order to make it more obvious what they do.

Only GeckoMVMContext really needs the flush, to measure scrolled height
afterwards. Do that explicitly.
This shouldn't change behavior, for the most part; there was a preload
test that relied on the flush when changing DPI to start a run really
clean, but other than that this looks green on try.
Should at best be neutral (just code clean-up), or be a performance
improvement.
In a follow-up, we can possibly remove the DelayedResize code from the
view manager, though I need to think how to possibly coalesce the MVM
reflows, so let's not do that yet.

Add a dom/base/rust crate called just "dom" where we can share these.
Most of the changes are automatic:
s/mozilla::EventStates/mozilla::dom::ElementState/
s/EventStates/ElementState/
s/NS_EVENT_STATE_/ElementState::/
s/NS_DOCUMENT_STATE_/DocumentState::/
And so on. This requires a new cbindgen version to avoid ugly casts for
large shifts.
