Add ECDSA secp256k1 verification Solidity tests

[Savio-Sou]

Context

Now that basic Solidity verifier tests have been reintroduced with #2997, it would be great to expand the tests to cover more barretenberg features exposed through Noir to better guarantee they work end-to-end from a Noir app dev perspective.

Problem

Out of all features, I would suggest prioritizing the testing of ECDSA secp256k1 verification given issues reported with the particular function:

• Failure to verify on-chain for bb.js-generated ecdsa signature verification #1844
• Failing on-chain verification of proofs containing ecdsa signature verification noir-lang/noir#3245

Adding the test for it asap should help provide further insights on how to debug the existing issues.

Objectives

(Open to discussion as I am in lack of barretenberg's technical context to judge if these make sense.)

Add tests that:

1. Generate a ECDSA secp256k1 verification proof
2. Verify the proof natively
3. Generate a corresponding Solidity verifier
4. Verify the proof via the Solidity verifier

Using:

1. Native barretenberg
2. bb binary
3. bb.js
