Allow activities in instrument cluster

- Added new CarInstrumentClusterManager to start activity in the cluster
and subscribe to cluster specific events
- Cluster vendor implementation (InstrumentClusterRenderingService) was
extended, now it can notify Car Service with ActivityOptions that holds
info how to launch activity in the cluster for specific category, also it
can send additional info such as unobscured bounds
(ClusterActivityState)
- added DirectRenderingClusterSample which is an example of vendor
implementation that utilizes new features
- added FakeClusterNavigationActivity in Kitchensink which is a dummy nav
activity that can be run in the cluster, it has appropriate permissions
and activity category in manifest

Test: kitchensink
