Camera: Update camera service to use new HIDL HALs, part 1

- Add CameraProviderManager
  - Enumerates individual camera provider HAL instances, as well
    as the devices they provide
  - Handles dynamic provider and device appearance/disappearance
  - Maps device names to public API namespace
  - Add unit tests for CameraProviderManager
- Add logic to enable new HIDL path
- Switch various bits of service internals to use string camera IDs,
  though leaving most camera1-facing bits using int IDs, since that's
  what the old API uses.
- Update CameraService to use CameraProviderManager instead of
  the legacy camera HAL
- Update clients to pass through provider manager to devices instead
  of just camera module
- Still TODO:
  - Update Camera3Device to use new HIDL interface
  - Update CameraHardwareInterface to use new HIDL interface
  - Update dump()
  - Update vendor tag handling

Test: New unit tests pass, camera CTS passes with Treble disabled
