deps: upgrade to libuv 1.39.0

Notable changes:

- uv_metrics_idle_time() and UV_METRICS_IDLE_TIME have been added
  for measuring the amount of time the event loop spends idle.
- uv_udp_using_recvmmsg() has been added to determine if a buffer
  is large enough for multiple datagrams should be allocated in
  the allocation callback of uv_udp_recvstart().
- On MinGW, the installation location has been updated to match
  Unix systems rather than Windows.
- uv_fs_copyfile() now tries to use copy_file_range() when
  possible.
- The test suite is now reported to pass on Darwin ARM64 (Apple
  Silicon).
- uv_{get,set}_process_title() now returns an error on platforms
  where uv_setup_args() is required, but has not yet been called.
- The _POSIX_PATH_MAX constant is no longer used, which could
  lead to buffer overflows in uv_fs_readlink() and
  uv_fs_realpath().
