Add AIDL Lights HAL to support multiple lights per type

Browse Source 
This is a revision of the previous 2.0 HIDL-based light HAL.
It accomplishes 2 goals:
 1) Support more than 1 light for a given type. This allows Assistant to
    use the HAL on TV platforms that have usually 4 indicator lights.
 2) Use AIDL, which is the more modern way of writing HALs.
The previous HAL is in hardware/interfaces/light/2.0 and the new one is
in versioned as aidl, as that supports forward compatibility.
