Original commit message:

    [base] fix builds with GCC 12 on certain Linux distributions

    With GCC 12 on certain Linux distributions (at least Debian 12,
    Alpine 3.18, Fedora 37, that ships GCC 12.2),
    std::is_trivially_copyable is broken
    and as a result, V8 fails to compile. This patch uses the
    same polyfill on MSVC to make it compile with GCC 12.2.

    See nodejs#45427 for more context.
