7f2c833a39 LibWeb: Implement CSSKeyframesRule.cssRuleList
To make this straightforward, CSSKeyframesRule now uses a CSSRuleList
for internal storage.

a12d28fd30 LibWeb: Implement CSSStyleDeclaration.parentRule
This readonly attribute returns the containing CSS rule, or null (in the
case of element inline style).

d6297ec074 LibWeb: Cast to the correct type in Element::auto_directionality()
Previously, we always cast to a HTMLInputElement when getting the value
of an auto directionality form associated element. This caused
undefined behavior when determining the directionality of an element
that wasn't a HTMLInputElement.

15a8baee03 LibWeb: Save time for animationcancel event before transitioning to idle
The if statement in the dispatch implies we are in the idle state, so of
course the active time will always be undefined. If this was cancelled
via a call to cancel(), we can save the time at that point. Otherwise,
just send 0.

f4e0c5395a LibWeb: Don't apply disabled adopted style sheets to the document
Previously, we would apply any adopted style sheet to the document if
its alternate flag was not set. This meant that all adopted style
sheets would be applied, since constructed style sheets never have this
flag set.

We have to unregister link element stylesheets from the old document's
StyleSheetList when moving them into a new document.

41667f969d LibWeb: Fix two problems where media queries didn't invalidate properly
There were two things going wrong here:

- Transformed text (via CSS text-transform) was not invalidated after a
  `@media` rule changed state.

- Removing the `style` attribute from an element didn't trigger a style
  update.

This fixes the regression in subtest 46 of Acid3.

Fixes #21777

4646a87eba LibWeb: Make CSSConditionRule.conditionText read-only
Previously @media rule conditions could be updated by assigning to
`conditionText`. This change aligns our implementation with the CSSOM
specification, which says `CSSConditionRule.conditionText` should be
read-only.

ed97946975 LibWeb: Support obsolete but required -webkit- CSS parsing quirk
As outlined in: https://www.w3.org/TR/selectors-4/#compat

We now do not treat unknown webkit pseudo-elements as invalid at parse
time, and also support serializing these elements.

bf16ddfbb0 LibWeb: Bail parsing transform-origin if the parsed value is null
Passing a value of a type different than number or length-percentage
to transform-origin returned a null pointer, and we didn't take care
of that path before.

This patch fixes a crash caused by an incorrect CSS declaration, such as
`transform-origin: "center"`.

c9c99b3c42 LibWeb: Produce resolved transform value according to spec algorithm
We now produce a `matrix3d()` value when appropriate.

Some sites (such as gsap.com) request the resolved style for `transform`
when there's no viewport paintable, but the element itself does already
have a stacking context. This fixes crashes in that case, because we now
do not access the stacking context at all.

We also do not wrap the result as a StyleValueList any more. The
returned StyleValue is only serialized and exposed to JS, so making it a
StyleValueList has no effect.

b8ede72107 LibWeb: Add a test for getComputedStyle()
Print out the value of each property in the computed-style of the body
element. This is by no means a thorough test that we're serializing
every property's value correctly in every configuration, (and in fact,
some are definitely wrong,) but it does give us a nice baseline.

0634d11318 LibWeb: Stop adding extra whitespace when serializing CSS Functions
Otherwise `attr(|name, "fallback")` becomes `attr(| name ,  "fallback")`

The test here is slightly aspirational. There are other rules for
serialization we don't follow (like stripping whitespace entirely from
many places) so these are marked with FIXMEs.

6f8be44c0e LibWeb+WebContent+headless-browser: Support async text tests
Previously, we used `on_load_finish` to determine when the text test
was completed. This method did not allow testing of async functions
because there was no way to indicate that the runner should wait for
the async call to end.

This change introduces a function in the `internals` object that is
intended to be called when the text test execution is completed. The
text test runner will now ignore `on_load_finish` which means a test
will timeout if this new function is never called.

`test(f)` function in `include.js` has been modified to automatically
terminate a test once `load` event is fired on `window`.
new `asyncTest(f)` function has been introduces. `f` receives function
that will terminate a test as a first argument.

Every test is expected to call either `test()` or `asyncTest()` to
complete. If not, it will remain hanging until a timeout occurs.

ff02de4ad0 LibWeb: Serialize StringStyleValue with quotes
In order to access the string's contents, use the new
`StringStyleValue::string_value()` method.

I think I found all the existing places that relied on
`StringStyleValue::to_string()` returning an unquoted string, but it's
hard to know for sure until things break.

6476dea898 LibWeb: Implement the math-depth CSS property
This one is a bit fun because it can be `add(<integer>)` or `auto-add`,
but children have to inherit the computed value not the specified one.
We also have to compute it before computing the font-size, because of
`font-size: math` which will be implemented later.

13e2ca6b59 LibWeb: Parse src: local(...) in CSS @font-face rules
Note that we don't load the local font as specified, but at least we no
longer reject such src properties in the CSS parser.

5955a504e0 LibWeb: Allow font-family names to start with -
We achieve this by making properties that accept a custom-ident value
skip the "someone else's vendor prefix" check for values that start with
a `-` character.

This fixes an issue where e.g `font-family: Arial, -apple-system` would
be rejected by the parser completely. We now treat `-apple-system` like
an identifier in such cases.

Also add `valid-types` metadata for the `font-family` property so this
actually works. :^)

fb727332f9 LibWeb: Decode linked style sheets before parsing them
This fixes an issue where a BOM at the head of a style sheet would be
passed verbatim to the parser, who would then interpret it as an ident
token and (after some confusion) fail to parse the first rule, but then
carry on with the rest of the sheet.

110eeb8591 LibWeb: Support calc(...) in box-shadow's values of type Length
The CSS box-shadow property takes 2-4 properties that are `<length>`s,
those being:
  - offset-x
  - offset-y
  - blur-radius
  - spread-radius

Previously these were resolved directly to concrete Lengths at parse
time, but now they will be parsed as LengthStyleValues and/or
CalculatedStyleValues and be stored that way until styles are later
resolved.

141143a1c6 LibWeb: Serialize custom properties in CSSStyleDeclaration::serialized()
Prior to this commit, PropertyOwningCSSStyleDeclaration::serialized()
did not include custom properties, which lead to an incomplete
`cssRule.cssText` result.
This commit makes that class also serialize the custom properties and
place them before the regular properties in the rule text.

a98f5c7251 LibWeb: Make resolved serialization of CSS display prefer short form
Although we translate e.g `block` to `block flow` for internal use in
the engine, CSS-DISPLAY-3 tells us to use the short form in
serializations for compatibility reasons.

This adds 9 points to our score on https://html5test.com/ :^)
