Investigate BlobstreamX contracts refactoring

[rach-id]

We should investigate if it is possible to simplify the BlobstreamX smart contracts architecture so that they're easy to deploy for new chains.

@rach-id when you get the chance, do mind adding / updating the acceptance criteria here to be more specific? Do we know what else is needed here before making a decision? do we know what we need from any refactors to make this worth it? Will switching to sp1 help this?

[rach-id]

Before SP1, we had the following contracts:

1. Circuit Verifier: verifies the proofs
2. SuccinctGateway: which is a registry for circuit verifiers and used to access control the verifiers
3. BlobstreamX contract

With SP1, we will have:

1. SP1 universal verifier: which verifies SP1 proofs. So we no longer need to deploy a verifier per circuit
2. BlobstreamX: where the logic in SuccinctGateway got moved to BlobstreamX

I don't think we can simplify the contracts anymore after moving to SP1. So I think we can close this.

Let me know if you agree so that I close.
