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().
