This is helpful in cases like a large <pre> element with text-wrap:nowrap and
text-overflow:ellipsis where there are many long lines, all of which get an
ellipsis rendered.

This is mostly the result of running ./mach static-analysis check --fix
with the new linter activated, with the following caveats:
- use std::fill when it makes sense
- use appropriate names for the loop target variable
- fix constness
- use array default initialization instead of an explicit loop when it
makes sense

I looked at this because in bug 2014331 I need to mark more pseudos as
element-backed, and it's kinda silly the state our setup is in right
now.
This is all a somewhat historical mess, because in the old style system
pseudo-elements were just atoms, and we had that different types of atom
setup. The source of truth for these right now lives in a header macro
file, which isn't very flexible.
But now we have PseudoStyleType which represents both pseudos and anon
boxes, and is similar to the rust side PseudoElement enum.
Plus, the ::-moz-tree pseudo-elements are defined as anon boxes which
doesn't make any sense, so move them to pseudo-elements while at it.
Unify this in a similar way we treat CSS properties: Source of truth is
in pseudo_elements.toml / anon_boxes.toml, and we generate Rust and C++
as needed. This allows removing the nsStaticAtom subclass thing from
XPCOM, too.
This avoids some nasty duplication around which pseudos are pref-gated
and what not as well.

This removes the implementation of nsHTMLButtonControlFrame, instead
reusing nsBlockFrame + align-content (or the relevant display type for
flex / grid / columns / etc).
This matches what Blink does and, for the most part, it is trivial.
It requires moving some special cases around, and override inline flow
display, tho so that buttons don't suddenly start fragmenting in the
inline axis.
It adds a tiny fix for a writing-mode mismatch in
nsBlockFrame::AlignContent(), covered by
layout/reftests/writing-mode/1138356-1-button-contents-alignment.html
containing-block-change-button tests are tweaked to avoid overflowing
the 600px viewport from WPT reftests causing scrollbar fuzziness.
contain-layout-baseline-005.html removes the <select> element just like
https://chromium-review.googlesource.com/c/chromium/src/+/5479489
removed the <button>s, since they align the same now, added a test for
that.

Convert `nsIScrollableFrame` to `ScrollContainerFrame` for all the APIs in
nsLayoutUtils, and then adapt other callers until everything compiles.

This simplifies our combobox code a bit more:
* Reflow() is only needed to compute the label isize.
* Frame construction uses a setup more similar to <input type=file> to
get the right frame tree, removing a bunch of special code.
* Lots of special code removed all over the place.

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).
