This patch computes the author-specified properties during the CSS cascade, and
removes the complex rule-tree-based implementation that tries to do the cascade
again.
This changes behavior in two ways, one of them which is not observable to
content, I believe:
* revert now re-enables the native styling. This was brought up in
https://github.com/w3c/csswg-drafts/issues/4777 and I think it is a bug-fix.
This is observable to content, and I'm adding a test for it.
* We don't look at inherited styles from our ancestors when `inherit` is
specified in a non-author stylesheet. This was introduced for bug 452969 but
we don't seem to inherit background anymore for file controls or such. It
seems back then file controls used to have a text-field.
I audited forms.css and ua.css and we don't explicitly inherit
padding / border / background-color into any nested form control.
We keep the distinction between border/background and padding, because the later
has some callers. I think we should try to align with Chromium in the long run
and remove the padding bit.
We need to give an appearance to the range-thumb and such so that we can assert
that we don't call HasAuthorSpecifiedRules on non-themed stuff. I used a new
internal value for that.

I think this should work for the animation throttling stuff.
Opacity works on the element tree, so I think this is sound.

The inclusions were removed with the following very crude script and the
resulting breakage was fixed up by hand. The manual fixups did either
revert the changes done by the script, replace a generic header with a more
specific one or replace a header with a forward declaration.
find . -name "*.idl" | grep -v web-platform | grep -v third_party | while read path; do
interfaces=$(grep "^\(class\|interface\).*:.*" "$path" | cut -d' ' -f2)
if [ -n "$interfaces" ]; then
if [[ "$interfaces" == *$'\n'* ]]; then
regexp="\("
for i in $interfaces; do regexp="$regexp$i\|"; done
regexp="${regexp%%\\\|}\)"
else
regexp="$interfaces"

interface=$(basename "$path")
rg -l "#include.*${interface%%.idl}.h" . | while read path2; do
hits=$(grep -v "#include.*${interface%%.idl}.h" "$path2" | grep -c "$regexp" )

D29542 fixed the bogus checks that was making nested pseudo-elements match
author rules. This adds tests and ends up being just a cleanup, though as it
turns out we it also fixes an issue with ::slotted() matched from
Element.matches.

We always include the combinator for pseudo-elements now (not including it was
just an optimization) in order to not match when nested pseudo-elements are
involved.
We could add a more generic check in `matches_simple_selector` like:
```
if element.is_pseudo_element() {
match *selector {
Component::PseudoElement(..) |
Component::NonTSPseudoClass(..) => {},
_ => return false,
}
}
```
But even that wouldn't be enough to make selectors like `:hover::marker` not
match on the `::before::marker` pseudo-element, plus that code is really hot.
So for now do the check on the `next_element_for_combinator` function. It's a
bit hacky but it's the best I could came up with...
While at it, simplify some checks to use is_pseudo_element() instead of
implemented_pseudo_element() directly.
Only the Rust patch as-is would make markers for ::before and ::after on list
items not show up, so we also need to switch ::marker to use ProbeMarkerStyle()
rather than ProbePseudoElementStyle(), since the marker should exist even if it
matches no rules.

This patch changes remaining things under `layout/`. However, there are some
places which still need to use `nsIPresShell`. That will be fixed in a
follow up bug.

This is more consistent with what the Rust bits of the style system do, and
removes a pointer from ComputedStyle which is always nice.
This also aligns the Rust bits with the C++ bits re. not treating xul pseudos as
anonymous boxes. See the comment in nsTreeStyleCache.cpp regarding those.
Can't wait for XUL trees to die.

There are a few mentions of nsRuleNode left but they are mostly
historical references so it makes sense to keep them.

This patch:
* Makes StyleStructID an enum class, and moves it to the mozilla namespaces.
* Introduces StyleStructConstants with some constants scattered through the
codebase.
* Makes the computed style bits an enum class, and splits mPseudoType and mBits
into their own members, since we were using a uint64_t when we have only a
couple flags and CSSPseudoElementType is a byte. We statically assert that
the number of style structs is less or equal to 32.
* Makes mPseudoTag, mPseudoType and mBits const, since we don't want them to be
mutated from C++, and we still need a few more refactorings (mostly getting
rid of FinishStyle) to avoid mutating ComputedStyle instead.
