This CL completes the conditional rule support for custom functions, along with CL:6227574 (@supports) and CL:6234272 (@media). @container is evaluated more dynamically than the other conditional at-rules, and therefore the existing invalidation path is sufficient for functional container queries as well. Note that ShadowDOM is ignored in this CL; we pass the wrong tree scope to CQ lookup currently (Issue 394500599). It makes sense to address this along with tree-scoped lookups of @function rules (Issue 394111301). I have also filed two follow-up tasks to avoid mutating MatchResult from StyleCascade (Issue 394500600), and for renaming HasContainerRelative- Units to something more accommodating (Issue 394353319).
