CC Mode: Don't fontify as types variables with the same names as struct tags
This fixes bug #58534.
* lisp/progmodes/cc-engine.el (c-forward-type): Only regard "struct" keywords
which create self contained types (e.g. C++'s "typename") as creating found
types.
* lisp/progmodes/cc-langs.el (c-self-contained-typename-kwds
(c-self-contained-typename-key): New language consts and variable.
