Documentation: guides: pipeline-handler: Update code, commands and logs

Browse source 
The pipeline-handler guide is a bit outdated:
- ControlList* in start() is now const.
- Registered pipeline handler log now comes from Camera log and the message is different.

Update the pipeline-handler guide to reflect these changes.
