feat: add Hash,[Partial]Eq to test utils

[giladchase]

This is useful for aggregator objects that want to keep track (via hashmap) of the number of contracts initialized inside a test.

In particular, a soon-to-be-added TransactionGenerator object will use this.

Done, kept Eq next to PartialEq though, they like it that way I think.

Hash makes it possible for FeatureContract to be a key in a hashmap.
