Though I think it may be slightly fishy if used in, e.g., a @keyframes block.
For our purposes right now it doesn't make a difference, I think.
Bug: 1466008
MozReview-Commit-ID: A7VCTOqaIuB
Currently, NAC always inherits from the closest non-NAC ancestor element,
regardless of whether it is for an element-backed pseudo or not.
This patch changes the inheritance so that for element-backed pseudos, we
inherit from the closest native anonymous root's parent, and for other NAC we
inherit from the parent.
This prevents the following two issues and allows us to remove the
NODE_IS_NATIVE_ANONYMOUS flag:
* Avoiding inheriting from the non-NAC ancestor in XBL bindings bound to NAC.
- This is no longer a problem since we apply the rule only if we're a
pseudo-element, and all pseudo-elements are in native anonymous subtrees.
- This also allows to remove the hack that propagates the
NODE_IS_NATIVE_ANONYMOUS flag from the ::cue pseudo-element from
BindToTree.
* Inheriting from the wrong thing if we're a nested NAC subtree.
- We no longer look past our NAC subtree, with the exception of
::-moz-number-text's pseudo-elements, for which we do want to propagate
::placeholder to.
A few rules from forms.css have been modified because they're useless or needed
to propagate stuff to the anonymous form control in input[type="number"] which
previously inherited from the input itself.

fix logic in overflow_direction, also add a FIXME
<!-- Please describe your changes on the following line: -->
This PR fix#19477, which the logic is obviously wrong.
However, it is impossible to add a test for this.
Due to #20867, the ` overflow_direction` is a hard code now. It never go to other conditions.
I add a FIXME there, and also add a SPEC link.

Fix for document salvageable state
I noticed a bug where if the document was un-salavageable due to the presence of `beforeunload` listeners, this could be overwritten if there were no listeners for `unload`. This could also have happened if an iframe of the document had no listeners while the parent did.

Pretty much the same setup we have for document.
We have the awkwardness of having to check containing shadow manually for
ShadowRoot because it's not available in TNode (and making it available added a
bit more complexity that wasn't worth it IMO).

Per bug 1322189 we really should. I've copied the setup we have already for
translate / scale, but we should really clean this up a bit more I'd think.
In any case, probably skew should be matched as well...

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.

Also call them "resolve" since it's the general term for computing something
