This parses `anchor-size(..)` functions in CSS, but does not yet result in a useful `Size`: we need style & layout interleaving similar to container queries for this, since the resulting value depends on layout results. Not supported yet: `anchor-size()` appearing inside a `calc()` node. Adds 4280 WPT subtest passes in `css/css-anchor-position`.
