Simplify `HashStable`



This PR:
- Simplifies the `HashStable` trait, by moving its generic parameter from the trait to its single method.
- Eliminates the need for the non-obvious `derive(HashStable)`/`derive(HashStable_Generic)` distinction.
- Reduces the need for, and clarifies, the non-obvious `derive(HashStable)`/`derive(HashStable_NoContext)` distinction.
