wpa_supplicant: Allow explicit wide channel configuration for AP mode

Browse Source 
Instead of deducing the wide (HT, VHT) channel configuration only
automatically in P2P mode, allow it to be configured in the network
in non-P2P mode.

Also allow all of these parameters to be configured through the control
interface or the configuration file.
