When codec supports multiple slices in one frame, VPU has to know when first slice of each frame is being processed, presumably to correctly clear/set data in auxiliary buffers.
Add first_slice field to cedrus_run structure and set it according to timestamps of capture and output buffers. If timestamps are different, it's first slice and viceversa.
