avcodec/vvcdec: fix boundary strength when IBC involved
The following cases should set bs to 1:
If the prediction modes are not the same.
If both prediction modes are MODE_IBC, but the motion vector delta is larger than 8 of 1/16 pixels.
see 8.8.3.5
How to reproduce it:
vvencapp -i sintel_trailer_2k_1080p24.y4m --preset fast --additional "IBC=1" -o sintel.266
ffmpeg -i sintel.266 -f md5 -
md5 will mismatch
