Make all UA widgets also NAC.
Keep the UA widget flag but break at anonymous subtree boundaries, so
that only nodes inside the UA widget directly (and not NAC from those)
get the flag.
This is important because two callers depend on this difference:
* The style system, since we still want to match content rules from
stylesheets in the UA widget. We also match user rules, which is a
bit sketchy, but that was the previous behavior, will file a
follow-up for that.
* The reflector code, since we want the scope for UA widgets to not
include the NAC nodes inside that UA widget. nsINode::IsInUAWidget
got it wrong.
After this patch, ChromeOnlyAccess is equivalent to
IsInNativeAnonymousSubtree, so we should probably unify the naming.
That's left for a follow-up patch because I don't have a strong
preference.

Implemented the scripting media feature.
Not locked behind a pref as it does not do anything new or particularly
give new data which could be used for fingerprinting (see <noscript>,
etc).
Also added new WPT tests (none previously). Not supported in any other
browsers yet.

If NaN is given as any input to CSS comp funcs (min/max/clamp), it

Now that we've removed nsXULScrollFrame, ScrollFrameHelper can be
subsumed under nsHTMLScrollFrame.
I want to do this before making scrollbars non-XUL.
Renaming to mozilla::ScrollFrame is left for a follow-up bug.

Make use of the new changes in the cssparser that allows 'none' keywords
in color components where allowed. We store the none values as 0.0 (as
per the spec) and mark the components with the flags. This way we don't
have to check anything on the components before doing calculations.
As this is the last part intended to be released for the new [color-4]
changes, I've also enabled the changes on nightly.

There are separate filters for IDs, classes, attribute local names, and
element state.
Also, we invalidate siblings of elements matched against the selector
list of :nth-child(... of <selector list>) by marking matched elements
with NODE_HAS_SLOW_SELECTOR_NTH_OF.
The only remaining invalidation case invalidation case is
`:nth-child(An+B of :has())` (bug 1818155), which should not block
shipping `layout.css.nth-child-of.enabled`, because :has(...) is still
being implemented (bug 418039).

Because restyle events cannot be posted for non-element nodes like the
shadow root, a child's siblings are restyled directly if its parent has
NODE_HAS_SLOW_SELECTOR or NODE_HAS_SLOW_SELECTOR_LATER_SIBLINGS but that
parent is the shadow root.
Drive-by, but braces were also added to some single-line "if" statements
in RestyleManager.

Implemented the prefers-reduced-transparency media query for all
platforms.
Windows and Mac have specific settings which are used, others (Android
and Linux/GTK) have it enabled if prefers-reduced-motion is also enabled
as there is no dedicated setting to check.
Locked behind new pref `layout.css.prefers-reduced-transparency.enabled`,
off by default always for now.
Also added new WPT tests (none previously).

Times like NaN and infinity are now parsed and serialized correctly.
Rewrote time to use `calc_clamping_mode` instead of `was_calc` to
stop some parse-time clamping which broke these values.
Adjusted WPT test expectations, 19 newly pass 🎉
Also added a new WPT test to cover a missing edge case:
`calc(1<unit> * NaN)` -> `calc(NaN * 1<canonical_unit>)`
The very similar angle tests do this already for angle's units.

Computed color values will not be in the correct format, closer to the
one specified by the author. This also means that colors accross the
code are stored now as AbsoluteColor or StyleAbsoluteColor. This allows
color space/gamut information to be available for use.
Some animation related test failures had to be changed, because colors
now has greater precision. Animated a color now causes a lot more
animation updates, which was not initially expected. See the bug for
discussion.

Per the spec update, the new syntax is:
`ray() = ray( <angle> && <ray-size>? && contain? )`
And for `<ray-size>`:
"If no <ray-size> is specified it defaults to closest-side."
So `<ray-size>` is optional and we omit it if it's default value, for
serialization.
By the way, offset=* properties are supported only in Gecko, so we don't
need a servo function to check the preference.
