feat: Add transaction message filter in GraphQL

[jinoosss]

Description

I added the data that is fetched by the query.
Then I decoded and processed the data in std.Tx and added filterable parameters.

• Add transaction message data
• Implement the filtering functions of the transaction filter model
• Separate the GraphQL schema

Example Usage

Querying transaction messages

{
  transactions(filter: {}) {
    hash
    # messages 
    messages {
      route
      typeUrl
      value {
        # Data in bank.MsgSend to query  
        ... on BankMsgSend {
          from_address
          to_address
          amount
        }

        # Data in vm.m_call to query  
        ... on MsgCall {
          send
          pkg_path
          func
          caller
          args
        }

        # Data in vm.m_addpkg to query  
        ... on MsgAddPackage {
          creator
          package {
            Name
            Path
            Files {
              Name
              Body
            }
          }
          deposit
        }

        # Data in vm.m_run to query  
        ... on MsgRun {
          caller
          send
          package {
            Name
            Path
            Files {
              Name
              Body
            }
          }
        }
      }
    }
  }
}

Filter transactio messages

{
  transactions(
    filter: {
      message: {
        route: bank 		# bank / vm
        type_url:  send	# send / exec / add_pacakge / run

        # Parameters for messages with route as `bank`  
        bank_param: {
          send: {
            # ...
          }
        }

        # Parameters for messages with route as `vm`
        vm_param: {
          m_call: {
            # ...
          }
          m_addpkg: {
            # ...
          }
          m_run: {
            # ...
          }
        }
      }
    }
  ) {
    hash
  }
}

The feature added seems ok, but it is really difficult to review because we have on the same PR a refactoring and a feature.

I would suggest keeping this PR as a feature implementation and avoiding refactors on the code.

@ajnavarro,
Thank you for your thorough review 🙏

Your comments have given me some direction.
It seems that the model is sufficient as a data passer, and I've changed it so that the resolver can handle the functionality.

[ajnavarro]

Really good work you did here. Just a few more comments UX related, and performance-related.

Thank you very much!

LGTM apart from a final request:

• Filter by params. Let me know what you think about that idea.

[ajnavarro]

I had been playing with the new GraphQL API and it is amazing the amount of info you can get, and how fast it is. I just added minor comments on schema parameters that are using uppercase moving them to lowercase for consistency.

I've gone through @ajnavarro's comments after my own review, and have to say that this looks amazing 💯

Thank you for contributing back to the tool, it really means a lot to the team 🙏
