libcamera: pipeline_handler: Add Camera properties

Associate to each Camera a ControlList which contains the Camera
properties as created by pipeline handlers in the pipeline handler's
CameraData and provide an operation to retrieve them.

Collect properties from the camera sensor in all pipeline handlers that
support one (IPU3, RKISP1 and VIMC).
