feat[vdpu383]: support 8K downscale mode

Browse Source 
Now there are 2 mode for downscale thumbnail frame buffer

1.MPP_FRAME_THUMBNAIL_MIXED (already use on RK3528 box):
Each buffer contains original output frame and 2x2 downscale
small frame, small image's buffer offset will be set in frame
meta info;
2.MPP_FRAME_THUMBNAIL_ONLY (newly added for rk3576 8K video):
for rk3576: vop & gpu does not support 8K frame,
in this case, mpp use 4K downscale buffer as decoder output
