Fix attestation withdrawals root mismatch (#4249)

## Issue Addressed

Addresses #4234 

## Proposed Changes

- Skip withdrawals processing in an inconsistent state replay. 
- Repurpose `StateRootStrategy`: rename to `StateProcessingStrategy` and always skip withdrawals if using `StateProcessingStrategy::Inconsistent`
- Add a test to reproduce the scenario
