libstdc++: Optimize std::is_scoped_enum compilation performance
This patch optimizes the compilation performance of std::is_scoped_enum
by dispatching to the new __is_scoped_enum built-in trait.
libstdc++-v3/ChangeLog:
* include/std/type_traits (is_scoped_enum): Use
__is_scoped_enum built-in trait.
(is_scoped_enum_v): Likewise.
