I am working on the ranges::to part of this (but not yet working on the new
container members).

commit r14-5794-g7a6a29c455e7755b501c0006e39beb4e56ec2729

libstdc++: Define std::ranges::to for C++23 (P1206R7) [PR111055]
This adds the std::ranges::to functions for C++23. The rest of P1206R7
is not yet implemented, i.e. the new constructors taking the
std::from_range tag, and the new insert_range, assign_range, etc. member
functions. std::ranges::to works with the standard containers even
without the new constructors, so this is useful immediately.
The __cpp_lib_ranges_to_container feature test macro can be defined now,
because that only indicates support for the changes in <ranges>, which
are implemented by this patch. The __cpp_lib_containers_ranges macro
will be defined once all containers support the new member functions.
libstdc++-v3/ChangeLog:
PR libstdc++/111055

As the commit log says, I've added the std::ranges::to functions, but not the
new members of the standard containers. I don't have immediate plans to add
those new members, so I'm unassigning myself from this bug for now.
