[libcamera-devel] [PATCH 08/10] libcamera: camera: Add Camera properties

Add an operation to the Camera class to retrive the Camera properties
registered by the pipeline handler.

While at it, rewords the Camera::controls() operation documentation to
specify that the camera control information are constant during the
camera lifetime not their value, while the camera properties value are
the actually static information.
