c++: add spellcheck suggestions for typedef etc. [PR77565]

Browse source 
cp_keyword_starts_decl_specifier_p misses many keywords that can
start decl-specifiers. This patch adds support for those keywords.

	PR c++/77565

gcc/cp/ChangeLog:

	* parser.c (cp_keyword_starts_decl_specifier_p): Handle more
	decl-specifiers (typedef/inline/cv/explicit/virtual/friend).

gcc/testsuite/ChangeLog:

	* g++.dg/spellcheck-pr77565.C: New test.
