libcamera: pipeline: rkisp1: Remove Timeline

There are no users left of the Timeline and there is no longer a need to
keep emulating a start of exposure event as the CSI-2 resciver reports
it. Remove the Timeline helper and what's left of it's integration in
the pipeline.

There is no functional change as nothing i the pipeline uses the
Timeline.
