PR libstdc++/90454.cc path construction from void*

Make the filesystem::path constructors SFINAE away for void* arguments,
instead of giving an error due to iterator_traits<void*>::reference.

        * include/bits/fs_path.h (path::_Path): Use remove_pointer so that
        pointers to void are rejected as well as void.
        * include/experimental/bits/fs_path.h (path::_Path): Likewise.
        * testsuite/27_io/filesystem/path/construct/80762.cc: Also check
        pointers to void.
        * testsuite/experimental/filesystem/path/construct/80762.cc: Likewise.
