Move `PlacementPolicy_ProcessSelectors` test. It tests how good
nodes were grouped into buckets after selection, but we can still query
full results and check them.

If weights for some buckets are equal, result depends on the
initial positions of buckets in slice. Thus we sort buckets by value
using hash of the first node as a have for the whole bucket.
This is ok, because buckets are already sorted by HRW.

* Implement `NodeInfo.EnterSubnet` method which adds node's subnet.
* Implement `NodeInfo.IterateSubnets` which behaves similar to
eponymous function from neofs-api-go/v2.
* Implement `BelongsToSubnet` which checks if `NodeInfo` describes the
node belonging to a specific subnet.
