LibWeb: Implement support for drawing with CanvasPattern
...
We already had the API, but drawing to the canvas was not affected by
any created CanvasPattern. This moves CanvasPatternPaintStyle to LibGfx
so we don't have to reach into LibWeb, and implements the plumbing to
let Skia use images as a fill pattern.

LibWeb: Mark canvas element for relayout when width or height changes
...
While width and height are presentational hints on canvas, they actually
map to the CSS aspect-ratio attribute, not to CSS width and height.
For this reason, we actually need to manually mark for relayout here.
Also import a WPT test that was flaky before this change.

LibWeb/HTML: Fix crash creating canvas pattern without context
...
This isn't a full fix, as the paint function does not handle this
either. But instead of getting the bitmap from the image source
immediately, follow the spec a bit more closely by creating the
CanvasPatern object with the ImageSource directly.
Fixes a crash for the 5 included WPT tests.

Tests: Create imported WPT test output from completion callback data
...
This allows us to disable test output, which performs expensive assert
tracking. This was making our imported tests run significantly slower
than tests run via `WPT.sh`.
Formatting the output ourselves also allows us to remove unnecessary
information from the test output.
This commit also rebaselines all existing imported WPT tests to follow
the new format.
