From: Jernej Skrabec <jernej.skrabec@xxxxxxxx>
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
the new_frame boolean of the context.

[hverkuil-cisco@xxxxxxxxx: rewritten to use the new_frame bool]
