The test case is a special case that changes focused element from a text control
to an editing host. Therefore, without a focus change, focused editor is
changed from a `TextEditor` to `HTMLEditor`. At this time, `IMEContentObserver`
needs to switch the observing target from the anonymous content if `<input>` to
children of it.
However, the editable content becomes completely changed without a focus change
in the DOM. Therefore, `IMEStateManager` needs to synthesize a fake focus move
for IME. Therefore, this patch make `IMEStateManager` recreate
`IMEContentObserver` if active one is not observing editable content for the
focused element under "current" conditions at checking it. (When
`IMEContentObserver` is being destroyed, it sends "blur" notification to IME
and the new `IMEContentObserver` instance posts "focus" notification with
all editable content data. I.e., recreating `IMEContentObserver` generates
a fake focus move from IME point of view.)
Additionally, there is the opposite case, that is, editing host of an `<input>`
whose type is not a text control may become a text control. Therefore, this
adds new WPTs to check the handler is the text editor for the text control or
the HTML editor. The tests passed on Firefox and Chrome at least.
FYI: I guess that in this case, we need to kick `focus` event listener of the
`HTMLEditor`, but anyway, users cannot change the content because it's the
case that an atomic content is the editing host. Therefore, I don't touch
about that in this patch.

Add a RAII helper to notify of multiple state changes together for
these.
The UpdateState CustomElementInternals calls that are getting removed
are unnecessary (the state should be up-to-date by then, there's nothing
changing there particularly).
Same for the call in nsGenericHTMLFormElement::UnbindFromTree. ClearForm
already does an state update.

This avoids a lot of useless time on things like GetValueAsDecimal(),
where we get the default value as a string, parse it as a number for
sanitization reasons, localize it to a string, just to parse it back to
a number.

It is always called from TextControlState, and always ends up in
TextControlState::ValueEquals, so we can avoid some indirection and just
use that.

It was introduced in bug 206859, but the `<input type="text">` in
`<input type="file">` was replaced with `<label>` in bug 345195.
Additionally, it's used only by `EditorBase` to check `<input type="text">`
is in `<input type="file">`. Therefore, we don't need it anymore.

We have more readable and faster versions (that just omit the namespace
arg).
Mostly done via sed, with a couple helpers to use the faster lookups
where possible.

Instead, lazily schedule evaluation of them before styling, much like we
were doing for SVG.
A subtle tweak is that we only remain scheduled while in the document.
This allows us to use the "in document" bit plus the "mapped attributes
dirty" bit to know our scheduled status. It also prevents doing silly
work for disconnected elements, and having to do hashmap lookups on
adoption and node destruction.

The issue here is that the SetValueInternal call made us go from empty
value to non-empty due to color's specialness of returning black always,
but since the value dirty flag wasn't set, the non-empty value actually
didn't make a difference and just confused the code.
Make the code follow the spec more closely, which fixes this (in
particular the SetDefaultValueAsValue call).
Also, remove some useless code in SetValueInternal() since callers end
up in OnValueChanged() effectively everywhere except when mDoneCreating
is false (in which case we can just wait until DoneCreatingElement calls
us again), and if the do not end up there then that's a bug to fix.

ParseAttribute ideally would be const (see bug 1829138), but the SVG and
SMIL code is rather messy. Still, now that BeforeSetAttr can't really
fail, swapping the order of ParseAttribute and BeforeSetAttr shouldn't
really change behavior.
Sorry for the extra `virtual` keyword removal and such. I had to do this
one by hand unlike the dependent bugs, and I went a bit drive-by, lmk if
you want me to split those changes.

Same rg + sed shenanigans as the first patch.
There were two that could fail, both due to OOM:
* HTMLInputElement::AfterSetAttr: If we fail (only in the type=range
case) we end up with an old value without it being clamped by
min/max/step.
* HTMLBodyElement::AfterSetAttr: If we fail we won't peek up the
DocShell's frame margins and styling could be incorrect.
That seems better than having to deal with broken states after we've
already set the attribute.

rg BeforeSetAttr -l | xargs sed -i 's/nsresult BeforeSetAttr/void BeforeSetAttr/g'
rg ::BeforeSetAttr -l | xargs sed -i 's/nsresult \(.*\)::BeforeSetAttr/void \1::BeforeSetAttr/g'
Plus trivial fixes, plus clang-format.
The only meaningful changes are in nsXULElement::BeforeSetAttr. Two
things could fail:
chromemargin: I removed it because we don't use the parsed attribute any
other place than here:
https://searchfox.org/mozilla-central/rev/31f5847a4494b3646edabbdd7ea39cb88509afe2/dom/xul/ChromeObserver.cpp#136
And that deals just fine with it not being parsed.
usercontextid: We have a debug assertion that we don't dynamically change it.
I kept it but I don't think it's worth failing to set the attribute on release for that
