CC Mode: Prevent lone ids being parsed as types unless in decl arglists

This fixes bug #59051.

* lisp/progmodes/cc-engine.el (c-forward-decl-or-cast-1): In the test for the
last invocation of c-fdoc-shift-type-backward before CASE 1, additionally
test CONTEXT not being an arglist or BACKUP-AT-TYPE being non-nil.
