This change adds two new treap iteration types: one for large unscavenged spans (contain at least one huge page) and one for small unscavenged spans. This allows us to scavenge the huge spans first by first iterating over the large ones, then the small ones. Also, since we now depend on physHugePageSize being a power of two, ensure that that's the case when it's retrieved from the OS. For #30333.
