Add the ability to start/stop supplicant to wificond

Introduce two new methods:

enableSupplicant()
disableSupplicant()

to IClientInterface.  These are used to start/stop
wpa_supplicant from controlling a given interface.
Today, they start/stop the wpa_supplicant service, but
in the future we may use them to add/remove the interface
from supplicant's control.

Bug: 30666540
Test: Can still connect to WiFi on bullhead.
