Fix T45778: Objects scaled to 0 cause black artifacts with Static BVH

The issue was caused by some numeric instability in triangle intersection which
was visible on avx2 CPUs and GPUs (at least sm_20 here) but maybe some others
too.

Committing rather a workaround for now to be safe for the release, still need
some investigation.

From tests with grass field from Gooseberry project didn't see measurable
slowdown.
