Migration of IRadio 1.3 types to 1.4.

To better test CBRS, we want IRadio 1.3 to be Android P plus CBRS
HAL interfaces, while 1.4 will be 1.3 plus all other Android Q
interfaces. So we are creating V1_4 folder and moving everything
currently defined in android.hardware.radio.V1_3 there.

Part 2: re-create 1.3 folder.
