PR libstdc++/86756 add std::filesystem::path to libstdc++.so

Move the C++17 std::filesystem::path definitions from the libstdc++fs.a
archive to the main libstdc++ library. The path classes do not depend on
any OS functions, so can be defined unconditionally on all targets
(rather than depending on --enable-libstdcxx-filesystem-ts). The tests
should pass on all targets too.
