libcamera: pipeline: simple: converter: Decouple input and output completion
The SimpleConverter API signals completion of input and output buffer pairs. This unnecessarily delays requeueing the input buffer to the video capture queue until the output buffer completes, and also delays signalling request completion until the input buffer completes. While this shouldn't cause large delays in practice, it will also not scale when multi-stream support will be added to the converter class. To address the current issue and prepare for the future, decouple signalling of input and output buffers completion.
