Automatic update from web-platform-tests [css-nesting] Support nested @layer rules This CL adds support for nested @layer rules, using the same boilerplate we use for other rules (@media, etc). This was not part of the initial release of css-nesting, because it was added to the specification too late in the process. However, the intent of the spec is to allow nesting of all at-rules that contain style rules in their body [1]. Renamed AllowedRulesType::kConditionalGroupRules to kNestedGroupRules, since it's not just conditional rules that are allowed to nest anymore.
