Since LIBCXX_ENABLE_FILESYSTEM now truly represents whether the platform supports a filesystem (as opposed to whether the <filesystem> library is provided), we can provide a few additional classes from the <filesystem> library even when the platform does not have support for a filesystem. For example, this allows performing path manipulations using std::filesystem::path even on platforms where there is no actual filesystem. rdar://107061236 Differential Revision: https://reviews.llvm.org/D152382
