This is enough to get the stylo-enabled build green.
There's still some orange in WPT with stylo disabled (due to interfaces not
exposed and that) that I'll update tomorrow.
Will send a different patch on top of this for that, though I'll land together.

More improvements to come. In particular, this still iterates through Shadow DOM
in each_xbl_cascade_data, but that should be changed later. That allows to
cleanup a bunch of stuff and finally fix Shadow DOM cascade order.
We still rely on the binding parent to be setup properly in the shadow tree, but
that requirement can go away later (we can walk the containing shadow chain
instead).
This mostly focuses on removing the XBL binding from the Shadow host.
It'd be nice to do EnumerateShadowRoots faster. I think that should also be a
followup, if needed.

Now that what we use to decide whether a document is styled by Servo are only
prefs and the doc principal, we don't need to inherit the style backend type,
since unless the pref has changed, the result will be the same.

If a single element is inserted in the document, from the lazy frame
construction path we mark it as the restyle root.
It has no restyle data, and we weren't calling ClearServoData when its parent
was being removed from ClearServoDataFromSubtree, thus leaving the stale restyle
root.

We used to do it this way effectively until I fixed it in bug 1400936.
Per the list of fuzz bugs that bug has in the "Depends on" field, some of those
without a super-clear fix, and others that aren't listed in there, and all the
complexity we had to deal with while receiving restyle requests mid-unbind, etc,
I think this is the right call.
This clears data on RestyleManager::ContentRemoved for non-anonymous nodes, and
on UnbindFromTree for subtrees rooted at anonymous nodes.
This will hopefully yield enforceable invariants.

The canvas prompt is extremely annoying. It happens everyone, automatically. And in
99.9% (not scientific) of cases it is not triggered by user input, but my automatic
tracking scripts.
This commit will automatically decline the canvas read if it was not triggered by
user input.
Just in case this breaks something irrepairably, we have a cutoff pref.
We don't intend to keep this pref forever, and have asked anyone who sets it to
tell us why.

The only remaining instance of NS_IMPL_BOOL_ATTR macro was expanded by hand.

This is particularly useful for knowing when it's safe to query for style and
layout information for a window without causing a synchronous style or layout
flush.
Note that promiseDocumentFlushed was chosen over promiseDidRefresh or promiseRefreshed
to avoid potential confusion with the actual network-level refresh of browsers or
documents.

Everyone calls them with the shell of the current composed document, and this
allows the multi-presShell stuff to just be in UpdateCurrentStyleSources /
DoGetStyleContextNoFlush.
The only reason we need to use OwnerDoc()->GetShell() instead of the composed
doc in GetStyleContext / GetStyleContextNoFlush is Element::GetBindingURL, which
does expect to get the binding URL for stuff outside of the composed doc (and
changing that gave me a useless browser).
That's technically a behavior change on the cases that used to pass nullptr, but
I think all callers are fine with that. I could also just add a special function
for that particular case, it may be worth it.
