Make SVM BOs more likely to get evicted than other BOs. These BOs
opportunistically use available VRAM, but can fall back relatively
seamlessly to system memory. It also avoids SVM migrations evicting
other, more important BOs as they will evict other SVM allocations
first.

Good point and at least of hand I can't think of anything which could go
wrong here.
Just keep an eye on potentially failing CI tests since we haven't really
exercised this functionality in recent years.
