a5d4f38fbe3bf71efd465d5260955bd6675765fd libstc++: std::formattable concept should not be defined for C++20
This concept was added by a C++23 proposal, so don't define it for
C++20.
Split the format/formatter/formatter.cc test into two parts, one that
tests the C++20 requirements and one that tests the C++23 concept.
libstdc++-v3/ChangeLog:
* include/std/format (formattable): Only define for C++23/
* testsuite/std/format/formatter.cc: Moved to...
* testsuite/std/format/formatter/requirements.cc: ...here.
* testsuite/std/format/formatter/concept.cc: New test.
* testsuite/std/format/functions/format.cc: Replace use of
std::formattable in C++20.
