Andreas Kling 61d79a1e47 LibWeb: Parse CSS image-set() ...

Add an abstract image style value for image-set() and parse both the
standard and -webkit-prefixed spellings through the existing <image>
value path. The parser accepts URL and string image candidates,
optional resolution descriptors, and type() filters.

Track attr-taint through substituted component values so image-set()
candidates using attr()-derived URL-producing tokens are rejected when
resolved for URL-using properties.

Update the relevant WPT baselines now that image-set() parsing is
supported in additional value contexts.
