Tim Gross 7d73065066 numa: fix scheduler panic due to topology serialization bug (#23284)
The NUMA topology struct field `NodeIDs` is a `idset.Set`, which has no public
members. As a result, this field is never serialized via msgpack and persisted
in state. When `numa.affinity = "prefer"`, the scheduler dereferences this nil
field and panics the scheduler worker.

Ideally we would fix this by adding a msgpack serialization extension, but
because the field already exists and is just always empty, this breaks RPC wire
compatibility across upgrades. Instead, create a new field that's populated at
the same time we populate the more useful `idset.Set`, and repopulate the set on
demand.
