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.

This is used to make the phone appear off by init
during late boot (e.x. fsck for disk health), so
it should shut off all lights (not just the screen).

This can be transitioned to by init to shutdown the
screen thereby preventing init from either depending
on binder or accessing halified sysnodes directly.
