✨ Hash Elements Enforce polymorphism in c#

### Is there an existing issue for this?

- [X] I have searched the existing issues

### Suggestion

The c++ hash elements function allows a variant array of objects to be passed in to the hash functions. The C interface also hides types through its use of opaque structs. The c# interface has a function `HashElems(string prefix, params ICryptoHashableType[] data)`. This enhancement is to enforce polymorphism for the 1ICryptoHashableType` and `CryptoHashableBase` components so that we do not need to use switch statements or boolean comparisons to determine the type of the object when hashing.
