  Add CustomStateSet and :state() selector
https://bugs.webkit.org/show_bug.cgi?id=215911

Reviewed by Tim Nguyen.

This adds the CustomStateSet idl definitions, and the `states` getter in
the ElementInternals IDL. The gatter laziliy initialises a
CustomStateSet object in ElementRareData which behaves like a
setlike<DOMString>.

This also adds the `:state()` pseudo selector, which can take an ident
and matches when the ident matches one of the given states in the
CustomStateSet for the element.

Any states set by CustomStateSet need to invalidate styles for the
element, so the `:state()` pseudo can match.
