* Split wifi feature into wifi-ap, wifi-sta and wifi-eap
* changelog
* Revert most of the changes, keep wifi and wifi-eap features only
* wifi-eap is unstable, include this feature into CI tests and documentation
* s/esp-radio-preempt-baremetal/esp-preempt/g
esp-preempt will hopefully one day be more useful than just a scheduler
for esp-radio, therefore I've removed the radio prefix for that future
goal. I also felt that baremetal didn't really add much other than
noise, so I've removed that postfix too.
