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.

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.

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

If the `.textContent` or `.defaultValue` attributes are used to change the content of a textarea,
according to the DOM Spec dictates first all children are removed and then a new child is added.
Removing all child elements must collapse the selection to 0.
However, the spec is not very precise on that matter,
see https://github.com/whatwg/html/issues/9028 .
This was currently not done (the selection was adjusted to the new length instead),
because the `Reset()` call was executed as a script runner,
therefore running (twice) after the new content has already been added.
With this change, the selection is adjusted to the new length explicitly
as soon as `ContentChanged()` is invoked, therefore updating it to 0
when content is removed.

A mutation caused by a call of `Text::SplitText` is handled by 2 method calls,
`CharacterDataChanged` and `ContentInserted`, in `nsRange`. Therefore,
`nsRange` stores some nodes for the later one, but
`HTMLTextAreaElement::ContentInserted` is called before it and that causes
another mutation which causes calling `nsRange::CharacterDataChanged` again.
Therefore, the assertion detects the recursive call.
For avoiding this issue, `HTMLTextAreaElement` needs to wait that all ranges
handle the mutation first. Fortunately, `ContentInserted` is called with a
script blocker (*1). Therefore, `HTMLTextAreaElement` can use script runner
to reset the anonymous subtree.

Add a dom/base/rust crate called just "dom" where we can share these.
Most of the changes are automatic:
s/mozilla::EventStates/mozilla::dom::ElementState/
s/EventStates/ElementState/
s/NS_EVENT_STATE_/ElementState::/
s/NS_DOCUMENT_STATE_/DocumentState::/
And so on. This requires a new cbindgen version to avoid ugly casts for
large shifts.

Should be much simpler and doesn't need to deal with the different
stuff. We already have pseudo-classes for this, :autofill and
:placeholder-shown.
I initially wrote this because this is the only limitation that forces
us to have the placeholder text as a direct child of the text control
frame. In the end I kept that as-is, but this simplification is still
worth it.
We remove dom.placeholder.show_on_focus because it doesn't behave
correctly (it doesn't match the :placeholder-shown pseudo-class and it
should). It was introduced in bug 807613 and never turned to false by
default. I suspect nobody will miss this, but if somebody complains
about it we can reintroduce it properly (handling the pref in DOM
instead, changing the right state bits).

There's no way to know whether the submission will actually be
validated, because formnovalidate on submit buttons is a thing (and even
if all the submit controls had formnovalidate, you could still submit
the form and validate it via form.submit()), so it seems better to make
these pseudo-classes not depend on this.
