    libstdc++: Add static_assert to std::integer_sequence [PR112473]

    C++20 allows class types as non-type template parameters, but
    std::integer_sequence explicitly disallows them. Enforce that.

    libstdc++-v3/ChangeLog:

            PR libstdc++/112473
            * include/bits/utility.h (integer_sequence): Add static_assert.
            * testsuite/20_util/integer_sequence/112473.cc: New test.
