    CC Mode: partially revert commit from 2022-10-04
    
    This reversion is of an ill-advised optimization, which resulted in non-type
    identifiers getting fontified as types.
    
    * lisp/progmodes/cc-fonts.el (c-fontify-new-found-type): Rather than writing
    the expected face directly to the text, instead remove the `fontified'
    property.  This allows the full font-lock mechanism to fontify the buffer
    correctly.
