Every public item needs rust doc.

Thanks. I think we need to document some warnings here though:
- Implementer must make sure that there are no collisions (same output for different inputs).
- Implementer must make sure that the same inputs lead to the same output (including environmental inputs like your storage location).
- Changing the implementation through a runtime upgrade without a proper storage migration would be a a catastrophic event.

Thanks for the suggestion. Appended them to the doc.

Background
We are using the pallet-contracts to implement phala's smart contract. We constructed a minimal substrate runtime which include only pallet-contracts and it's dependencies. The runtime then can runs on multiple seperate storage instance. The problem is that contracts instantiated in different storage instance can have the same address, and we want the address to be unique in global.
Summary
To solve the problem, this PR adds a type parameter to generate ink addresses. The DefaultAddressGenerator keeps the original formula. And users can customize the address generation formula by implement a custom AddressGenerator.
