    libstdc++: Fix path::generic_string allocator handling (PR 94242)

    It's not possible to construct a path::string_type from an allocator of
    a different type. Create the correct specialization of basic_string, and
    adjust path::_S_str_convert to use a basic_string_view so that it is
    independent of the allocator type.

            PR libstdc++/94242
            * include/bits/fs_path.h (path::_S_str_convert): Replace first
            parameter with basic_string_view so that strings with different
            allocators can be accepted.
            (path::generic_string<C,T,A>()): Use basic_string object that u=
ses
the
            right allocator type.
            * testsuite/27_io/filesystem/path/generic/94242.cc: New test.
            * testsuite/27_io/filesystem/path/generic/generic_string.cc:
Improve
            test coverage.
