Backport following Wifi fixes:
1. Optimize WiFi sleep in WiFi/BT coexist mode
I> If any data TX/RX in WiFi slice, force wakeup next TBTT
II> Increase active timeout to coex TBTT to avoid sleep in WiFi slice
2. Fix esp_wifi_stop() crash
esp_wifi_stop() crashes if it's called when WiFi is not initialized.
3. Fix WiFi log print level
4. Return fails if AP's configuring AP channel is out of range
5. esp_wifi_sta_get_ap_info() returns actual values of group ciphers
Currently CI test environment is complicated, usually includes NIC, AP.
These devices are not used for a lot test cases. Therefore we split the
test environment, remove unnecessary devices. Then it will be easier to
create CI runners.
1. The test step for error code REASON_ASSOC_EXPIRE is not reliable. SoftAP
could also send error code WIFI_REASON_NOT_AUTHED
2. STA will be disconnected now if softAP restart DHCP server
