libstdc++: Use __promote_3 for std::hypot [PR121097]
The __promoted_t alias is only defined when __cpp_fold_expressions is
defined, which might not be the case for some hypothetical C++17
compilers.
Change the 3-arg std::hypot to just use __gnu_cxx::__promote_3 which is
always available.
libstdc++-v3/ChangeLog:
PR libstdc++/121097
* include/c_global/cmath (hypot): Use __promote_3 instead of
__promoted.
