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.
