Table captions have a similar issue as column spanners, where their
parent might not be the in the subtree of the style frame of its
ancestors. In particular, a repaint posted to a table that
doesn't cause a repaint in the table wrapper might not cause a repaint
of its captions.
Handle table captions like we treat out of flows and spanners, and add
more comments around this set-up.

Right now, we reconstruct frames in response to a change in the CSS
`contain` property or `content-visibility`. This patch tries to optimize
this a bit:
1. Updates involving style containment change continue to force a
reconstruction, due to the need to handle counters/quotes.
2. Updates involving paint/layout containment change only force a
reconstruction if it's needed to handle absolutely/fixed
positioned descendants or floats (for this one, see also bug 1874826).
3. Other containment changes will only force a reflow and repaint.
Per the CSS contain spec, layout, style and paint containments are
enabled for `content-visibility: hidden` and `content-visibility: auto`.
As a consequence, changing `content-visibility` between `hidden` and
`auto` values no longer requires reconstruction. Changing between these
values and `visible` may need a reconstruction although authors may
generally avoid that in practice by forcing `style` containment.

Use the non-native styles instead. I needed a hack in RestyleManager to
deal with paint invalidation properly. It's a pre-existing issue for
native checkboxes / radio.

Extend the per-frame-class bit we have to devirtualize IsLeaf to also
devirtualize IsFrameOfType. That is, move this data to FrameClasses.py.
This was done by going through all the frame classes, trying to preserve
behavior.
The only quirky thing is that I had to add two more trivial frame
classes, `nsAudioFrame` for audio elements, and
`nsFloatingFirstLetterFrame`. That's because these frame classes were
returning different answers at runtime, but they do this only on
conditions that trigger frame reconstruction (floating, and being an
audio element, respectively).

This patch removes the old docshell timeline and timeline markers codebase and replaces them with equivalent Gecko profiler marker. This patch also fixes Bug 1834143, which is a subset of 1421651.

This is technically web-exposed, but if we needed to introduce it for
compat we could always re-introduce it matching false.

This patch adds an API to count the number of restyles triggered by animations. This API will replace the existing timeline marker based testing of the animation/restyle system.

Upcoming :has invalidation (Bug 1792501) requires 4 more flags, and we're out of space.
This change consumes the remaining 32-bit hole in `nsINode` to migrate selector-specific
node flags.
This has implications on 32-bit platforms, specifically on text nodes.

This patch introduces functional pseudo parameters, i.e. `::highlight(foo)`,
for `getComputedStyle()`. This required adapting the parse algorithm (`nsCSSPseudoElements::ParsePseudoElement()`) and forwarding the functional pseudo parameter into the style engine.
