deps: upgrade to libuv 1.31.0

Notable changes: - UV_FS_O_FILEMAP has been added for faster access to memory mapped files on Windows. - uv_fs_mkdir() now returns UV_EINVAL for invalid filenames on Windows. It previously returned UV_ENOENT. - The uv_fs_statfs() API has been added. - The uv_os_environ() and uv_os_free_environ() APIs have been added.
