The pipeline-handler guide is a bit outdated: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.

There is no need to pass the Camera pointer to queueRequest(),
completeBuffer() and completeRequest() as the Request also passed
contains the same information. Remove the Camera argument to avoid
situations where the information in the Request and the argument differ.
There is no functional change and no public API change as the interface
is only used between the Camera and PipelineHandler.

Applications now have the ability to pass in controls that need to be
applied on startup, rather than doing it through Request where there might
be some frames of delay in getting the controls applied.
This commit adds the ability to pass in a set of libcamera controls into
the pipeline handlers through the pipeline_handler::start() method. These
controls are provided by the application through the camera::start()
public API.
