io_uring: Add io_uring command support for sockets
Enable io_uring commands on network sockets. Create two new SOCKET_URING_OP commands that will operate on sockets. In order to call ioctl on sockets, use the file_operations->io_uring_cmd callbacks, and map it to a uring socket function, which handles the SOCKET_URING_OP accordingly, and calls socket ioctls. This patches was tested by creating a new test case in liburing.
