Add test for checking mv projection clamping

This clip crashes on frame 67 if the projection is not clamped (ref: dav1d!1023 (merged)). Incorrect motion vector selections starting from frame 65 eventually leads to symbol overread on frame 67.

Concerns I have with merging this:

1. At least on my machine, this test takes 10s to run, which is significantly longer than every other test. For comparison, the rest of the tests take 60s total for my machine to run. I'm not sure how to fabricate a smaller test case with the same issue, but that would probably be more ideal.
2. This is a very short clip from a Japanese television show. I am not sure what is the policy regarding using test data sourced from copyrighted materials.
