    libstdc++: Move start_lifetime_as functions to bits/stl_construct.h
[PR106658]

    This allows inplace_vector to use these functions without including the
entire
    <memory> header.

    Preprocessor checks are changed to use __glibcxx macros, so new functions
are
    available outside memory header, that exports __cpp_lib macros.

            PR libstdc++/106658

    libstdc++-v3/ChangeLog:

            * include/bits/stl_construct.h (std::start_lifetime_as_array)
            (std::start_lifetime_as): Moved from std/memory, with update
            to guard macros.
            * include/std/memory (std::start_lifetime_as_array)
            (std::start_lifetime_as): Moved to bits/stl_construct.h.
