libcamera: vimc: Report sensor timestamp
Report the sensor's timestamp in the Request metadata using the completed buffer timestamp. The buffer's timestamp reports the video capture buffer processing time, and it does not theoretically matches the 'start of exposure' definition. VIMC being a testing platform and the test driver completes the buffers for each media entity connected in the pipeline one after the other, the current solution is acceptable for the pipeline.
