If the UA sheet gets parsed with the pref off, and then the pref gets
flipped on, we don't re-parse the UA sheet (nor we want to).
Enable the property in UA sheets unconditionally so that the test passes
even when the browser was started-up with the container queries pref
off.

The fix is calling set_outline_style so that we also reset the actual
outline width. Also clean-up surrounding code a little bit to be
marginally more efficient, and do the same change for border-*-style
(which was doing the right thing, but it's better to make sure both stay
in sync).

For example, inline elements may have container-type:size but they don't
support size containment, so @container(width >= 0) shouldn't match.

'container-type' and 'content-visibility' can trigger various kinds of
containment, but this was done via nsStyleDisplay::EffectiveContainment,
to avoid affecting the computed value of 'contain'.
This was fine except for style containment, which needs to set the flag
SELF_OR_ANCESTOR_HAS_CONTAIN_STYLE in order to really work, but this was
only done with 'contain: style'.
So this patch removes nsStyleDisplay::EffectiveContainment, and instead
uses two fields for containment: mContain and mEffectiveContainment.
This is somewhat analogous to mDisplay and mOriginalDisplay, though in
that case the computed value is the modified display.
Also fixes a typo in IsContainStyle() that made it return true for any
kind of containment, not just for style containment.

This makes relatively simple changes so that we check lowercase-ness of
local-name selectors first. If so, we don't need to check whether we're
an HTML element in an HTML document, which requires a fair bit of
pointer-chasing.

This doesn't seem necessary anymore. It was originally added to disable
unions, which is now done with disable_untagged_union.

And hide internal but used values. System fonts are not exposed in the
computed style so this should be fine.
If we need the old values for some obscure reason, it's trivial to alias
them to e.g., menu or so.

It's unclear to me when they were disabled, but we do want to enable
these as otherwise there's no way to catch bindgen issues that can end
up in subtle bugs at best, or memory corruption at worst.

This reduces the weird interactions that can appear on menus.
This also progresses BiDi support, including for accesskeys.
