libcamera: camera: Pass Private pointer to Camera constructor

In order to allow subclassing Camera::Private in pipeline handlers, pass
the pointer to the private data to the Camera constructor, and to the
Camera::createCamera() function.

The Camera::Private id_ and streams_ members now need to be initialized
by the Camera constructor instead of the Camera::Private constructor, to
allow storage of the streams in a pipeline handler-specific subclass of
Camera::Private.
