Migration of IRadioConfig 1.1 types to 1.2.

To better test CBRS, we want IRadio 1.1 to be Android P plus CBRS
HAL interfaces, while 1.2 will be 1.1 plus all other Android Q
interfaces. So we are creating V1_2 folder and moving everything
currently defined in android.hardware.radio.config.V1_1 there.
