[css-shapes] Implement polygon() round modifier (#60345)
* [css-shapes] Implement polygon() round modifier
Implement the CSS Shapes `polygon(round <length>, ...)` syntax behind
the CSSPolygonRounding runtime flag.
This adds parsing and serialization for the optional round modifier,
stores the radius on polygon basic shapes, includes it in equality and
interpolation, and generates rounded polygon paths for clip-path,
offset-path, and related basic-shape consumers.
For shape-outside, rounded polygons now rasterize from the rounded path
instead of the sharp vertex list so float exclusion follows the rounded
outline.
Add unit tests, a clip-path rendering test, and WPT coverage for parsing
and computed values.
