Add missing CSSValue::addDerivedHash implementations to types that formerly were part of CSSPrimitiveValue
https://bugs.webkit.org/show_bug.cgi?id=315514

Reviewed by Antti Koivisto.

Implements `addDerivedHash` on ident and string-like CSSValue
subtypes that have been extracted from CSSPrimitiveValue by
hooking them up to the `add(Hasher&, {type})` implementations
for their underlying strong type.

This hashing is used by ImmutableStyleProperties::createDeduplicating
to deduplicate style property lists.
