[SPIKE] - Batch Validation of VRFs

### Business Hypothesis
The cryptography team has completed the VRF batch optimization work, and it is ready to be released, along with a corresponding KES improvement.

This is ready for release and requires a hard fork.

The Consensus team needs to evaluate a solution and determine the complexity and scope of work needed to enable batch VRF validation.

### Drivers
-improve performance around epochs

### Functional Requirements

### NFRs

### External Dependencies
-None

### DoD
-acceptance criteria met
-QA testing completed
-audits completed
-benchmarks pass, no significant regressions
-merge to mainnet/release branch
