Camera: Add default implementation of camera.device@3.3

Inherit as much as possible from camera.device@3.2

- Refactor CameraDeviceSession@3.2 implementation to separate out the
  HIDL session interface from the main implementation object. This
  avoids multiple inheritance issues
- Create CameraDeviceSession@3.3 with support for the new
  overrideDataspace field
- Add virtual factory method for CameraDevice to create the right version
  of Session.
- Create CameraDevice@3.3, which overrides createSession to return a
  CameraDeviceSession@3.3.
- Add system property to override selection of which minor HIDL
  version is used for legal HAL version 3.x; set the default to the
  newest available minor version.

Test: Camera CTS passes on device using @3.3.
