[FFmpeg-devel] [PATCH v1 2/2][GSoC 2024] tests/checkasm/vvc_mc: for SAD, only test valid subblock sizes

[Stone Chen]

According to the VVC specification (section 8.5.1), the maximum width/height of a subblock passed for DMVR SAD is 16. This along with previous constraint requiring width * height >= 128 means that  8x16, 16x8, and 16x16 are the only allowed sizes.

This changes check_vvc_sad() to only test and benchmark those sizes.
