Removes some duplicated code, and removes the property when the observer hash
table is empty (there's no reason to keep it around).
The keeping the property around is causing issues because we want to change
intersection observers on adopt.
Right now when that happens, we create a property on the new document, but then
override it with the transferred one if present.
We should instead merge the properties rather than transferring them to the new
document, or something. But not keeping the empty property mitigates the
problem.
We should still fix that though, I'll file another bug for it.

nsPresContext.h is only used for unit conversion, which can be done by Units.h
in a similar fashion.
PresShell.h was needed for some capturing-content stuff which can be moved out
of line.

I thought this would fix <input type=number style="user-select: none">, but
turns out it doesn't.
<input type=number> doesn't have the editor root as a root of the anonymous
subtree, so the current hack wouldn't work, as the anon root wouldn't have the
editable flag. So tweak the code a bit to handle stuff in a simpler way than
setting the flags after the fact, and set the NAC-root flag earlier to avoid
the mOuterWrapper->AppendChildTo(root) call forgetting about root's flags.
I had to tweak one AccessibleCaret test, but that's because it uses <textarea>
with user-select: none, and our behavior there is not particularly sane. It just
happened to work because that test-case also had a bunch of contenteditable
elements, and we stop matching this rule:
https://searchfox.org/mozilla-central/rev/220a3bd6063fcbe5ca50e88dcabdc7dee0aca448/layout/style/contenteditable.css#22
Because the anonymous div now properly matches :-moz-read-write, which made the
rule apply and the test work. See comment 4 of this bug.
I'll fix this stuff up and add some tests for our behavior here in bug 1611699.
I refactored the dragdrop tests to cover more input types, but I ended up not
being able to use them because they're dependent on the content.
Instead I added an extra test and changed the refactor so that it applies to
<input type=search>, as there's layout work going on in bug 558594, and it'd be
unfortunate to regress this there too.

It removes a script blocker. Therefore, although it depends on the caller
whether it causes running script or not. However, we should mark it as
`MOZ_CAN_RUN_SCRIPT` for safer code.
It's called only by the destructor of `nsAutoCauseReflowNotifier`. Therefore,
this patch also marks its constructor as `MOZ_CAN_RUN_SCRIPT` for making
each creator method marked as `MOZ_CAN_RUN_SCRIPT` or
`MOZ_CAN_RUN_SCRIPT_BOUNDARY`.
Most of the creators is mutation listener methods. However, `PresShell`
does nothing after destroying `nsAutoCauseReflowNotifier`. Therefore,
this patch does not change the callers in MutationObserver.cpp to use
`RefPtr<PresShell>` at calling them because changing it may cause performance
regression.
Perhaps, we should create another methods of `WillCauseReflow()` and
`DidCauseReflow()` to avoid unnecessary `MOZ_CAN_RUN_SCRIPT` marking.
However, I'm not sure whether most callers may run script or not because
of outside of my knowledge.

This changeset is a simple find and replace of `MOZ_FALLTHROUGH` and `[[fallthrough]]`.
Unfortunately, the MOZ_FALLTHROUGH_ASSERT macro (to assert on case fallthrough in debug builds) is still necessary after switching from [[clang::fallthrough]] to [[fallthrough]] because:
* MOZ_ASSERT(false) followed by [[fallthrough]] triggers a -Wunreachable-code warning in DEBUG builds
* but MOZ_ASSERT(false) without [[fallthrough]] triggers a -Wimplicit-fallthrough warning in NDEBUG builds.

Sub classes of `nsITextControlElement` are only `HTMLInputElement` and
`HTMLTextAreaElement`. And both base class is
`nsGenericHTMLFormElementWithState`. Therefore, we can make
`nsITextControlElement` inherit `nsGenericHTMLFormElementWithState` and
make `HTMLInputElement` and `HTMLTextAreaElement` inherit
`nsITextControlElement`. Then, we can get rid of a lot of QI between
`nsINode`/`nsIContent`/`Element` and `nsITextControlElement` (and note that
some of them in a hot path).
Additionally, this patch renames `nsITextControlElement` to
`mozilla::TextControlElement`.

The amount of XUL elements with non-null binding-parent pointer should be
equivalent to HTML now that XBL is gone.
Shadow DOM already has the extended slots for both the binding parent and

But don't hook it into style yet, that'll be a follow-up patch.
I had this patch in my local queue for a bit and there was no point in not
landing it I guess.
The value of this attribute could be stored only in the shadow root (as this
only applies to shadow hosts), but that would make invalidation harder, I think,
so do the obvious thing for now.

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.
