nrf_wifi: Wait for command status from firmware

After sending the command, wait for command status event from firmware.
There are two scenarios. Either firmware sends a specific event for the
command or a generic event (NRF_WIFI_UMAC_EVENT_CMD_STATUS) where it
states about the command failure/success.

This commit is related to wait for NRF_WIFI_UMAC_EVENT_CMD_STATUS and
it's handling.

For commands expecting specific events will be added later.
