After bug 1632647, we can have pseudo-classes inside :not / :is /
:where, which the invalidation and matching code weren't handling.
Add a few tests for this stuff working as expected.

That way we can look at the parent dependency as described in the previous
patch. An alternative would be to add a:
parent_dependency: Option<&'a Dependency>
on construction to `Invalidation`, but this way seems slightly better to avoid
growing the struct. It's not even one more indirection because the selector is
contained directly in the Dependency struct.

Some of the stuff, in particular inside GeckoBindings stuff should be
refactored to be less ugly and duplicate a bit less code, but the rest of the
code should be landable as is.
Some invalidation changes are already needed because we weren't matching with
the right shadow host during invalidation (which made existing ::part() tests
fail).
Pending invalidation work:
* Making exportparts work right on the snapshots.
* Invalidating parts from descendant hosts.
They're not very hard but I need to think how to best implement it:
* Maybe get rid of ShadowRoot::mParts and just walk DOM descendants in the
Shadow DOM.
* Maybe implement a ElementHasExportPartsAttr much like HasPartAttr and use
that to keep the list of elements.
* Maybe invalidate :host and ::part() together in here[1]
* Maybe something else.
Opinions?

This patch invalidates the style for `::selection`, which will restore the
behavior before the regression.
However, it's still not quite correct, because repaint is not triggered. Given
that `::selection` requires some major change to implement
https://github.com/w3c/csswg-drafts/issues/2474, we can address this problem
later.

Still does nothing, since we still do not collect part rules, but this is all
the plumbing that should allow us to invalidate parts when attributes or state
change on their ancestors.

We could invalidate in a slightly more fine-grained way, but I don't think it's
worth the churn vs. keeping the special-cases minimal.

This avoids threading the quirks mode and nth-index cache around, and prevents
having to thread even more arguments down for the querySelector stuff (at least
VisitedHandlingMode and the style scope).

We only use it to get the quirks mode, and a shared style context is a pretty
heavy-weight struct.
