samples: wifi: Add Wi-Fi and Thread coexistence sample

Initial version of the Wi-Fi and Thread coexistence sample.

This sample is to run Wi-Fi and Thread throughputs simultaneously
to show how they coexist.

Wi-Fi in station mode connects to Wi-Fi AP and runs Zperf.
Thread in child mode connects to leader and runs Zperf.
