[Utils] Support class template specializations in update_cc_test_checks ClassTemplateSpecializationDecl not within a ClassTemplateDecl represents an explicit instatiation of a template and so should be handled as if it were a normal CXXRecordDecl. Unfortunately, having an equivalent for FunctionTemplateDecl remains a TODO in ASTDumper's VisitFunctionTemplateDecl, with all the explicit instantiations just being emitted inside the FunctionTemplateDecl along with all the other specializations, meaning we can't easily support explicit function instantiations in update_cc_test_checks.
