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.
