Should std.compat provide 3-argument hypot overloads in the global namespace?

MSVC STL's std.compat intentionally doesn't provide them in the global namespace (https://github.com/microsoft/STL/pull/3108). I think this possibly makes sense, and we may submit an LWG issue to exclude them from the global namespace. However, for libstdc++, such exclusion would slightly complicate the implementation.

As per https://github.com/microsoft/STL/issues/3945 we should support the std module in C++20 mode too.
