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.

The inclusions were removed with the following very crude script and the
resulting breakage was fixed up by hand. The manual fixups did either
revert the changes done by the script, replace a generic header with a more
specific one or replace a header with a forward declaration.

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`.

This would've made my life a lot easier. There's a couple things that don't
match the spec that I've left as comments.

This expands Element with chrome-only setAttribute methods that give devtools
callers an ExtendedPrincipal with a CSP with a flag set to allow changes to
inline styles. This gives devtools the ability to modify documents with a
Content-Security-Policy.

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
containing shadow root.

This was generated with:
```
rg -l -g '*.{cpp,h}' MOZ_XBL . | while read FILE ; do

```
After this, I manually removed the directive in nsContentUtils.cpp due to:
unifdef: ./dom/base/nsContentUtils.cpp: 4630: Unterminated string literal
unifdef: Output may be truncated

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.

In that case, the flat tree cannot possibly be changing, so we don't really need
to invalidate anything. This, in theory, is just a really minor optimization.
In practice however, the browser chrome needs it, at least for now, because XUL
elements get frames really early (because we don't have lazy frame construction
for XUL, bug 1584935), and because destroying some kinds of frames (like panels)
does have side effects (they're popups), even though ideally they shouldn't.

It was complaining about
