bb89a958e5 Add AIDL Lights HAL to support multiple lights per type 
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.

Test: atest VtsHalLightTargetTest

b944d69508 blank_screen: shut off all lights 
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).

64a7afb07e Add 'blank_screen' util. 
This can be transitioned to by init to shutdown the
screen thereby preventing init from either depending
on binder or accessing halified sysnodes directly.

Bug: 70846424
Test: manual + init use
