binder: Reset internal states after network params update

Couple of changes in the CL:
1. Add the necessary wpa_supplicant internal state machine
resets after params updation.
2. Notify the wpa_supplicant core when bssid is changed on a network. This
is used by wpa_supplicant to notify the driver whether roaming is allowed or
not.

BUG: 1252274
TEST: Ran 'wpa_supplicant_binder_test'
