libcamera: software_isp: Handle queued output buffers on stop

When SoftwareIsp stops, input and output buffers queued to it may not
yet be fully processed.  They will be eventually returned but stop means
stop, there should be no processing related actions invoked afterwards.

Let's stop forwarding processed output buffers from the SoftwareIsp
slots once SoftwareIsp is stopped.  Let's track the queued output
buffers and mark those still pending as cancelled in SoftwareIsp::stop
and return them to the pipeline handler.

Dealing with input buffers is addressed in a separate patch.
