libcamera: PipelineHandler: Move printing pipeline names to CameraManager

Since pipeline registration is done with declaring static factory
objects, there is a risk that pipeline factories will be constructed
before libcamera facilities are ready. For example, logging in the
constructor of a pipeline handler factory may cause a segfault if
threading isn't ready yet. Avoid this issue by moving printing the
registration of the pipeline handler to the camera manager.
