lavc/qsvenc: add Tiles encode support for HEVC
Add -tile_rows and -tile_cols option to specify the number of tile rows
and columns for ICL+ (gen 11) platform.
A tile must wholly contain all the slices within it. Slices cannot cross
tile boundaries. So the slice number would be implicitly resized to the
max(nSlice, nTile).
Example:
ffmpeg -v verbose -hwaccel qsv -init_hw_device qsv=hw
-filter_hw_device hw -f rawvideo -s:v 1920x1080 -i ./input.nv12 -vf
format=nv12,hwupload=extra_hw_frames=64 -c:v hevc_qsv -tile_rows 2
-tile_cols 2 -slices 4 -y output.h265
Also dump the actual quantity of encoded tiled rows and columns in run
time.
Fix the enhancement #8400.
