fb975cc156 LibWeb/CSS: Correct how we evaluate boolean media-features
The spec has a general rule for this, which is roughly that "If it's not
a falsey value, it's true". However, a couple of media-features are
always false, apparently breaking this rule. To handle that, we have an
array of false keywords in the JSON, instead of a single keyword. For
those always-false media-features, we can enter all their values into
this array.

Gets us 2 more WPT subtest passes.

00617884a6 LibWeb/CSS: Correct our scan media-feature
Despite what the spec suggests, modern displays are not progressive, and
WPT expects `@media (scan: progressive)` to fail. So, return `none`
here to accurately represent that.

I've left a FIXME in case we can detect the display type from the OS
somehow in the future.

Gets us 4 WPT subtest passes.

9fe8445946 LibWeb/CSS: Maintain original form of media-feature ranges
Previously, for `foo < 30px` ranges, we'd flip them and store them as
`30px > foo` instead. That worked fine, but means the serialization is
wrong. So instead, keep them in their original form.

I experimented with giving Range two optional sub-structs instead of 4
optional members, thinking it would be smaller - but it's actually
larger, because the two Optional<Comparison>s fit snugly together. So,
the slightly-goofy all-Optionals remains.

This gets us 2 WPT passes that I'm aware of.

9b8dc6b8d0 LibWeb/CSS: Parse media-feature values forgivingly
Instead of rejecting invalid media-feature values at parse time, we are
expected to parse them, and then treat them as Unknown when evaluating
their media query. To implement this, we first try to parse a valid
value as before. If that fails, or we have any trailing tokens that
could be part of a value, we then scoop up all the possible
ComponentValues and treat that as an "unknown"-type MediaFeatureValue.

This gets us 66 WPT passes.

b577302f07 LibWeb/CSS: Make media type and feature evaluation combination explicit
Functionally this is the same before, as result is always True or False
before this point, and `True && Foo` evaluates to `Foo`. But this is
more clearly correct, instead of correct by coincidence.

a4d3c62524 LibWeb/CSS: Return a MatchResult from MediaFeature::compare()
This commit on its own has no observable behaviour changes, as we still
only return True or False, but for the next commit, we'll need to be
able to return the Unknown state here, and without this change we'd get
regressions.

fe7bac73f0 LibWeb/CSS: Stub out a function for serializing ComponentValue sequences
This is very hacky and wrong, but it means there's one place to fix,
instead of one for UnresolvedStyleValue, and one for invalid
MediaFeatureValues which I'm about to implement.

38aca62ef5 LibWeb/CSS: Make media-type more permissive
The current spec defines this simply as `<ident>`, but does apparently
serialize as lowercase.

Because of this change, we no longer need to care about the deprecated
media types, as they all behave the same as unknown ones.

We still keep an enum around for KnownMediaType, to avoid repeated
string comparisons when evaluating it.

Gets us 2 WPT passes.

6711438e0d LibWeb: Ensure anonymous wrappers inherit inline-block display
When restructuring a block node inside an inline parent, if the
nearest block ancestor is `display: inline-block`, ensure that
the generated anonymous wrappers also have `display: inline-block`.
This fixes layout issues with block elements nested
inside inline-block elements.

09f5ce42f6 LibWeb: Ensure floats are correctly placed under the preceding float
Previously floats would be placed next to the highest float that
fitted the new float on its line. However, this violates the rule
that floats should be placed under the preceding float if it does
not fit next to it.

8b787020a2 LibWeb: Delay the document load event while re-fetching <object> images
We are required to delay the load event while any fetch is ongoing. We
currently have a very hacky re-fetch for images to go through the shared
resource request infrastructure. We must delay the load event during
this re-fetch.

This becomes an issue in an upcoming commit to import the acid2 test.

b1ee539e9d LibWeb: Fix font-style to slope conversion
In a recent refactor of font styles, the new FontStyleStyleValue was
introduced; however, the `to_font_slope()` function was not changed to
understand this new type. When it tries to convert such a font style to
a keyword, it fails. We then rendered the wrong font-style.

36da270dbe LibIPC+LibWeb: Flush MessagePort messages before closing
The spec isn't super clear on what disentagling a MessagePort means. But
we are required to send all pending messages before closing the port.

This is a bit tricky because the transport socket performs writes on a
background thread. From the main thread, where the disentanglement will
occur, we don't really know the state of the write thread. So what we do
here is stop the background thread then flush all remaining data from
the main thread.

Fixes a bug that reproduces with the following steps:
1. Create an object with a getter for property "a" in its prototype,
   where the getter adds an "a" property to the object itself.
2. Call the "a" getter in a loop for the first time. This triggers
   caching of metadata indicating that the "a" property is located in
   the prototype chain.
3. Call the "a" getter in a loop for the second time. Oops, the cache
   says the getter is in the prototype chain, but the object now
   also has its own "a" property that was added by the first getter
   call.
