Saving Consensus Parameter in TopLevel state for light client

[majecty]

Foundry is saving ValidatorSet and Chain Parameters in top-level state even though Foundry can query the information to a module. They are saved in top-level state for the light client.

We need to design how light client works and how they use modules and revisit this issue.

Currently, we don't have explicit design and requirements for light client.

FYI, ConsensusParameter = ValidatorSet + ChainParameter
