3799. Should <math.h> provide 3-argument ::hypot overloads?

Discussion:

See also LWG 3782(i). Like lerp, neither <math.h> nor C compatibility is mentioned in P0030R1, and MSVC STL decides not to declare 3-argument hypot overloads in the global namespace (perhaps so does libc++).

Perhaps we should also avoid providing these overloads in the global namespace. However, such change seems a bit difficult for libstdc++'s <math.h>.

[2022-11-01; Reflector poll]

Set priority to 3 after reflector poll. "This affects the exports of std.compat".
