Same idea, when only one node is slotted or unslotted, we only need to
do work for the rest of assigned nodes iff the slot has dir=auto or a
dir=auto ancestor, and the result of computing the dir=auto ancestor
changes.
Otherwise we just need to propagate the directionality from the slot.

This ensures that styles from UA widgets apply. Turns out they look
pretty much right without them, but there's a bug in nsDateTimeBoxFrame
where we rely on the styles in order for the baseline to be sensible.

Also, for changes in CSS declarations, like changing
cssRules[i].style.color or something, we end up avoiding a lot of the
work we were doing.
This page still trips us in the sense that they add a stylesheet, then
call getBoundingClientRect(), then insert more rules in the stylesheet,
which causes us to rebuild a lot of the cascade data.
We could try to detect appends to the last stylesheet on the list or
something I guess, and avoid rebuilding the cascade data in some cases.

This also fixes some other bits, like mAdoptedStyleSheets.ElementAt(0) (which
really should be "the first applicable adopted stylesheet") and so on. Added a
test for that.
The new invariant also implies that a DocumentOrShadowRoot can't appear twice in
StyleSheet::mAdopters.
Also clears adopted stylesheets in Document::ResetStylesheetsToURI, as it's the
right thing to do (if you hit that code path with constructable sheets you'd end
up asserting, as we'd call FillStyleSetDocumentSheets after and find sheets in
there). I don't quite have a test-case for that though.

When XBL is disabled, no code in dom/xbl will be built. Also, adds ifdefs
to remove any of the XBL related code elsewhere. There's definitely more
that can be done here, but I think it's better to wait to do the rest of
the cleanup when we actually remove the code.

This penalizes a bit non-shadow-DOM content, in exchange of making Shadow DOM
slightly faster as well.
The biggest advantage of this is that all ContentRemoved notifications would see
the flattened tree before the changes, which is something a11y needs to be
correct.
XBL would still not be handled right by a11y, but that's not new and content
cannot do random stuff with XBL so it's not too bad.

I need this to make style invalidation work with Shadow Parts in a way that's
fast. If something in the ancestor shadow root or any of its ancestor changes,
that makes a ::part() selector change, I don't want to walk the whole shadow
tree over and over in order to find the parts that I need to restyle.
Unfortunately we cannot just use the mutation observer setup from ShadowRoot
since, unlike for slotted elements, there's no restriction of where a part can
appear in the shadow tree.
That means that the regular nsIMutationObserver notifications don't quite cut
it, since we'd get notified only of subtree roots and we'd need to tree-walk
around in order to figure out if we have any new part.
I thought that I was going to be able to share more code with other bits if I
moved them away from nsIMutationObserver, thus bug 1554498, but in the end it
was not the case, so here's the "without bug 1554498" version of the patch.
The patch on top of that bug (that as I mention in the commit message I'm
ambivalent about whether we should land or not) should be pretty similar either
way.

BindContext was going to have way more information at first, but then I realized
that most of the things I wanted to know were basically a flag away using the
parent node.
Still I think it's worth it, now experimenting with BindToTree will only mean
adding a field to a struct that's included from a couple cpp files, instead of a
massive pain.
I also think this is clearer, and doing this highlights quite a few
inconsistencies in our code which I've left untouched, but commented with
FIXMEs.
Steps are:
$ for file in $(rg 'nsresult BindToTree\(' | cut -d : -f 1 | sort | uniq); do sed -i 's#nsresult BindToTree(Document\* aDocument, nsIContent\* aParent,#nsresult BindToTree(BindContext\&, nsINode\& aParent)#g' $file; done
$ for file in $(rg 'nsresult BindToTree\(' | cut -d : -f 1 | sort | uniq); do sed -i 's# nsIContent\* aBindingParent) override#override#g' $file; done
$ for file in $(rg '::BindToTree\(' | cut -d : -f 1 | sort | uniq); do sed -i 's#::BindToTree(Document\* aDocument, nsIContent\* aParent,#::BindToTree(BindContext\& aContext, nsINode\& aParent)#g' $file; done
$ for file in $(rg '::BindToTree\(' | cut -d : -f 1 | sort | uniq); do sed -i 's#nsIContent\* aBindingParent)##g' $file; done

$ ./mach clang-format
