avcodec/vvcdec: ensure every CTU belongs to a slice

Browse Source 
According to section 6.3.3 "Spatial or component-wise partitionings,"
CTUs should fully cover slices with no overlaps, gaps, or additions.
No overlaps are ensured by task_init_parse.
No gaps and no additions are ensured by this patch.
