    libstdc++: Improve Doxygen documentation groups [PR 101258]

    This defines some new Doxygen groups for C++17 variable templates and
    for the contents of <experimental/type_traits>. By documenting the group
    as a whole and adding each template to a group we don't need to document
    them individually.

    Also mark more internals with "@cond undocumented" so that Doxygen
    ignores them by default. Also make Doxygen process <experimental/simd>.

    For some reason, many of the class templates in <type_traits> do not
    appear in the "Metaprogramming" group. For example, add_cv,
    remove_extent, and all the is_xxx_constructible and is_xxx_assignable
    traits. For some reason, Doxygen doesn't include them in the group,
    despite doing it correctly for other traits in the same header.

            (COLS_IN_ALPHA_INDEX): Remove obsolete tag.
            (PREDEFINED): Add/fix some more macros that need to be expanded.
            * include/bits/random.h: Stop Doxygen from documenting internal
            implementation details.
            * include/bits/random.tcc: Likewise.
            * include/bits/this_thread_sleep.h: Fix @file name.
            * include/experimental/bits/simd.h: Add to Doxygen group. Do not
            document internal implementation details.
            * include/experimental/bits/simd_detail.h: Do not document
            internal implementation details.
            * include/experimental/simd: Define Doxygen groups.
            * include/experimental/type_traits: Improve documentation for
            the header file. Define groups. Use @since commands.
            * include/std/scoped_allocator (scoped_allocator_adaptor): Move
            declaration before undocumented region.
            * include/std/type_traits (true_type, false_type): Use using

            (is_invocable_v, is_nothrow_invocable_v, is_invocable_r_v)
            (is_nothrow_invocable_r_v): Move definitions next to other C++17
            variable templates.
            Do not document internal implementation details. Move misplaced
            group-end command. Define group for variable templates.
            * include/std/variant: Do not document internal implementation
            details.
