Add module_query_safe to appropriate queries

[Taztingo]

Summary

None of our deterministic queries have been marked with option (cosmos.query.v1.module_query_safe) = true;. This means that we cannot take full advantage of them and allow them to be used by the internal state machine.

Problem Definition

This prevents new features in cosmos-sdk from correctly using our chain, and it allows informs devs which queries they can safely use.

Proposal

1. Find all queries that are classified as safe. They have the following attributes:

• The query tracks gas usage.
• The query has a deterministic response.

2. Add option (cosmos.query.v1.module_query_safe) = true; to each query that we classify as safe.
3. Regenerate protos.
