Support Passpoint frame filters in Android
The conf->hs20 flag is not used in Android, but HS 2.0
configuration is still required when setting up the frame filters
in the WPA driver. Split the is_hs20_network() to two functions,
and moved the conf->hs20() check to a new is_hs20_config function.
Added ANDROID compilation flag in hs20_configure_frame_filters()
to skip the configuration check.
Additionally, trigger a call to hs20_configure_frame_filters()
upon succesful connection when state equals to WPA_COMPLETED.
Bug: 168681498
Test: Verify wpa driver is called with the appropriate frame filter
flags when connecting to Passpoint networks.
Test: Verify wpa driver is not called to filter frames for other
Enterprise networks.
