wifi: wfx: implement wfx_remain_on_channel()
With some conditions, the device is able to send/receive frames during
scan operation. So, it is possible to use it implement the "remain on
channel" feature. We just ask for a passive scan (without sending any
probe request) on one channel.
This architecture allows to leverage some interesting features:
- if the device is AP, the device switches channel just after the next
beacon and the beacons are stopped during the off-channel interval.
- if the device is connected, it advertises it is asleep before to
switch channel (so the AP should stop to try to send data)
