190745fd58 LibWeb/CSS: Parse initial value using syntax from @property 
Now we pass all WPT tests in:
`css/css-properties-values-api/at-property-cssom`.

Note: Failing tests were false positives.
Proper handling of inheriting values and detecting computational
independence will be done in another PR.

c4f5e7bee3 LibWeb: Implement anchor-size(..) function parsing 
This parses `anchor-size(..)` functions in CSS, but does not yet result
in a useful `Size`: we need style & layout interleaving similar to
container queries for this, since the resulting value depends on layout
results.

Not supported yet: `anchor-size()` appearing inside a `calc()` node.

Adds 4280 WPT subtest passes in `css/css-anchor-position`.

11e2dbb555 LibWeb/CSS: Support text-justify: distribute legacy value alias 
...for `text-justify: inter-character`.

We previously had this mapped in Enums.json, but the behaviour is
different: `a=b` in Enums.json keeps `a` around but makes it behave the
same as `b`. A legacy name alias is instead expected to replace `a`
with `b`, so we have to do that separately.

4ee8110449 LibWeb: Handle flood-opacity in line with other opacity properties 
We now do the proper thing in terms of:
 - Allowing percentages
 - Returning the computed value in getComputedStyle
 - Handling values out of the [0,1] range

Gains us 13 WPT passes in the imported tests.

1d3e539c09 LibWeb: Account for logical property groups in set_a_declaration 
When setting a declaration for a property in a logical property group,
it should appear after all other declarations which belong to the same
property group but have different mapping logic (are/aren't a logical
alias).

Gains us 1 WPT pass.

927cd969b2 LibWeb: Generically serialize "positional-value-list-shorthand"s 
We were previously handling this ad-hoc via logic in
`get_property_internal` but this didn't cover all contexts (for
instance `CSSStyleProperties::serialized`.

Gains us 9 more WPT tests as we now cover properties which weren't
included in the previous ad-hoc approach.

78b6032940 LibWeb: Validate operator count when parsing a calculation 
Previously, we would allow calc values such as `calc(min(1 2))`, which
would be simplified to `calc(3)` because we assumed that numbers not
separated by an operator represented a sum. We now validate that the
number of operators we see is as we would expect before collecting
these values into a sum node.

8e9753eadb LibWeb: Correctly compute consistent type when simplifying hypot
