Wrong chroma ALF virtual boundary position for 4:2:2 and 4:4:4 sequences

Reported by: nanhu Owned by:

Component: spec Version: VVC D9 vB

In R2001-v3, for 422 and 444 sequences, wrong chroma ALF VB position is defined.

CtbSizeY - 4 is used as ALF VB position for all color components and all chroma formats. However, for chroma components in 422 and 444 sequences, CtbSizeY - 2 should be use.

Suggested fix is attached.
