Add config to skip state toggle off/on for Wi-Fi NAN

If STA and NAN share the same iface wlan0, Wi-Fi vendor HAL service
sends eventDisabled to NAN framework when STA setMacAddress to wlan0.
This disables NAN when STA is turned on.

Since NAN always uses its own random MAC instead of using MAC of STA,
this action is not necessary and gets NAN kicked off for no benefits.

We add a build time configuration to optionally disable this behavior.
