libstdc++: Implement C++20 std::chrono::parse [PR104167]
This adds the missing C++20 features to <chrono>.
I've implemented my proposed resolutions to LWG issues 3960, 3961, and
3962. There are some unimplemented flags such as %OI which I think are
not implementable in general. It might be possible to use na_llanginfo
with ALT_DIGITS, but that isn't available on all targets. I intend to
file another LWG issue about that.
libstdc++-v3/ChangeLog:
