  [css-values] Implement rcap / rex / ric / rch units
https://bugs.webkit.org/show_bug.cgi?id=260648
rdar://114367871

Reviewed by Cameron McCormack.

Implement new units as per https://drafts.csswg.org/css-values/#font-relative-lengths

Invalidation support is also added by invalidating when the root font cascade / line height changes.

Also add a bunch of tests for root font units in monospace.
