[cli] add UDP socket openness check before sending with `udp send` (#10206)

Problem: Executing the `udp send` command in CLI without previously
opening the example udp socket results in an unhandled null-pointer
exception.

Solution: Before anything is processed in the
`UdpExample::Process<Cmd("send")>(Arg aArgs[])` method, the UDP socket
is checked whether it's open or not. If not, the method returns with
OT_ERROR_INVALID_STATE error avoiding the null-pointer exception.
