0b0ad5c9db LibWeb: Calculate width property resolved value correctly 
This means that relative width values are now correctly resolved when
calling `getComputedStyle()`.

517379ff80 LibWeb: Resolve basic-shape clip-paths 
These will be ignored within SVGs (for now SVGs only support <clipPath>
elements), but will allow clipping standard HTML elements.

5f17d9b34a LibWeb: Add BasicShapeStyleValue to represent CSS basic shapes 
See: https://www.w3.org/TR/css-shapes-1/#basic-shape-functions

This patch only implements the `polygon()` basic shape (with the rest
left as FIXMEs).

b7526a39b0 LibWeb: Expose StyleComputer's FontLoader class publicly 
We'll want to explicitly load fonts from FontFace and other Web APIs
in the future. A future refactor should also move this completely away
from StyleComputer and call it something like 'FontCache'.

d76167b8a4 LibWeb: Add CSS ParsingContext constructor with a realm and URL 
This is useful for when we want to parse paths relative to the current
ESO's api base url when there isn't a document, such as in a Worker
context.

bd4f516e64 LibWeb: Stub out FontFaceSet.status and .ready attributes 
WPT wants to check these properties before running ref tests.
This fixes a ton of crashes in our CI WPT runs.

2bc51f08d9 LibWeb: Implement or stub FontFace interface's attribute getters/setters 
We only support parsing half of these, so the ones we don't recognize
get a friendly exception thrown.

3a5eabc43b LibWeb: Rename CSS::FontFace to CSS::ParsedFontFace 
This implementation detail of CSSFontFaceRule is hogging the name of a
Web API from CSS Font Loading Module Level 3.

464d7d5858 LibGfx+LibWeb: Allow inexact size lookups when requesting scaled fonts 
For bitmap fonts, we will often not have an exact match for requested
sizes. Return the closest match instead of a nullptr.

LibWeb is currently the only user of this API. If it needs to be
configurable in the future to only allow exact matches, we can add a
parameter or another method at that time.

493a04d5fe LibJS: Add PropertyLookupPhase enum to distinguish Object [[Get]] calls 
We can now tell the difference between an own property access and a
subsequent (automatic) prototype chain access.

This will be used to implement caching of prototype chain accesses.

3945e1a82a LibJS: Make JS::Cell a Weakable 
This makes things easier downstream of Cell, and is preparation for
using weak pointers in prototype chain property caches.

02a8966b61 LibWeb: Serialize empty media rules with a single newline

this.

a2cccf9420 LibWeb: Use correct spacing when serializing media features

if the title field is empty.

bad44f8fc9 LibWeb: Remove Bindings/Forward.h from LibWeb/Forward.h 
This was resulting in a whole lot of rebuilding whenever a new IDL
interface was added.

Instead, just directly include the prototype in every C++ file which
needs it. While we only really need a forward declaration in each cpp
file; including the full prototype header (which itself only includes
LibJS/Object.h, which is already transitively brought in by
PlatformObject) - it seems like a small price to pay compared to what
feels like a full rebuild of LibWeb whenever a new IDL file is added.

Given all of these includes are only needed for the ::initialize
method, there is probably a smart way of avoiding this problem
altogether. I've considered both using some macro trickery or generating
these functions somehow instead.

384b18b271 LibWeb: Make parse_color_stop_list() a CSS Parser method 
This lets us remove the color/dimension-parsing lambdas, since these
always forwarded to the same methods. This will make it easier to later
convert those methods to take a TokenStream.

The list is already kept sorted. Removing one sheet anywhere from the
list will not make it unsorted.

bf1c82724f LibWeb: Default to an empty string when a string attr substitution fails 
When a string-type attr() substitution produces no value and no fallback
had been specified, the spec mandates we default to the empty string.

d5cddd4696 LibWeb: Unset stylesheet properties when removing from a StyleSheetList 
Previously, the parent CSS stylesheet, owner node and owner CSS rule
properties were not unset when removing a sheet from a StyleSheetList.

This change moves the methods for adding and removing sheets to and
from a StyleSheetList, directly into the StyleSheetList class and
ensures they are called as required by the CSSOM specification.

037b395b5d LibWeb: Try to parse WOFF and WOFF2 even if MIME type says otherwise 
As it turns out, websites can lie about this, and it doesn't really cost
us much to try decoding as other formats before giving up.

4b1abcf61d LibWeb: Generalize support for dimension attributes 
Rather than each element which supports dimension attributes needing to
implement parsing the attributes and setting the appropriate style, we
can generalize this functionality. This will also make each element more
closely resemble the spec text, as we will be effectively declaring, for
example, "The img element supports dimension attributes" in code.
