That way color pickers work even when this setting is on. We always know that
pseudo-element style attributes are trusted.

If you're in a shadow tree, you may not be slotted but you still need to look at
the slotted rules, since a <slot> could be a descendant of yours.
Just use the same invalidation map everywhere, and remove complexity.
This means that we can do some extra work while trying to gather invalidation
if there are slotted rules, but I don't think it's a problem.
The test is ported from https://cs.chromium.org/chromium/src/third_party/WebKit/LayoutTests/fast/css/invalidation/slotted.html?l=1&rcl=58d68fdf783d7edde1c82a642e037464861f2787
Curiously, Blink fails the test as written, presumably because they don't flush
styles from getComputedStyle correctly (in their test they do via
updateStyleAndReturnAffectedElementCount), due to <slot>s not being in the flat
tree in their implementation.

Optimize selector matching for some common cases
This is the "better way" I mentioned in #19774, which seems to actually improve the score of dromaeo_css on talos.

In total, this PR saves ~60k.
The conditional compilation on the _Debug FFI function eliminates one
of the ToCss variants, eliminating 54.4k, as well as a bunch of other
<1k functions. Removing the public trait implementation of Debug for the
font metrics provider eliminates the last Debug impl from stylo.

style: Remove -servo-text-decorations-in-effect
It is bogus, because it depends on the display property as it's cascaded, but
the display property can change afterwards, for example, if we get blockified
because we're the root element or a flex item.
Replace it with a normal field instead.
Also, it carries some weight, because it's the last property that uses this
concept of "derived" property, and "custom cascade". So we can remove some code
after this.
Compute it after the cascade process in StyleAdjuster.

For the `fn set_original_display` inside `properties.mako.rs`, I removed `is_item_or_root` first to see how the tests result is. If it's needed, I'll add it back.

style: Add a document state invalidator.
Don't use it yet (since I was working from a Servo tree). Will hook it up and improve in the Gecko bug.
Right now it takes a `StyleRuleCascadeData`, which means that if all the origins in the document have state selectors we could do just one walk over the tree and not multiple, that will be improved.
Other than that, this is completely untested of course, but I prefer to land it, given I don't think it's complex, and work on the Gecko integration separately. The reason for this is that I also plan to fix the `<slot>` bugs, which will change `StyleRuleCascadeData` and such, and I want the two bugs to conflict as little as possible.

All TElement's implement Copy, and are just pointers, so the double indirection
is stupid.
I'm going to try to see if removing this double-indirection fixes some
selector-matching performance, and this is a trivial pre-requisite while I wait
for Talos results.
