Adds Occupant Awareness System APIs via a new service and corresponding manager.

The OAS APIs include detection data for:
(1) Presence detection (does the person exist at each seat location).
(2) Gaze detection (where is the person looking and for how long).
(3) Driver monitoring (is the driver looking on-road and for how long).

This change includes the new API surface. However, the service is not yet connected via HAL to the underlying detection graph. That functionality will come in a subsequent change.

Bug: 142383440

Test: Unit tests
