Handle the C++ "identifiers" "final" and "override" correctly.
This fixes bug #24319, allowing destructors affixed with these identifiers to be correctly fontified. * lisp/progmodes/cc-engine.el (c-forward-type, c-forward-decl-or-cast-1): After reaching the "end" of a type expression, skip over any occurrences of c-type-decl-suffix-ws-ids-key. * lisp/progmodes/cc-langs.el (c-type-modifier-kwds): Remove "override" and "final" from the C++ value. (c-type-decl-suffix-ws-ids-kwds, c-type-decl-suffix-ws-ids-key): New lang constants/variables for "final" and "override".
