libstdc++: Adjust <format> for Clang compatibility [PR107712]

Clang doesn't define __builtin_toupper, so use std::toupper.

Also add some (not actually required since C++20) typename keywords to
help Clang versions up to and including 15.

libstdc++-v3/ChangeLog:

	PR libstdc++/107712
	* include/std/format (__format::__formatter_int::format): Use
	std::toupper when __builtin_toupper isn't available.
	(basic_format_arg::handle): Add 'typename'.
	* include/std/complex (complex<T>): Add 'typename'.
