Merge #6175: feat: allow resigning for EHF

6f82a56171 feat: add option to AsyncSignIfMember to allow signing same requestID on different msgHashes (pasta)

Pull request description:

  ## Issue being fixed or feature implemented
  Please see: https://www.dash.org/forum/index.php?threads/ehf-activation-issues.55146/ for a description of this issue

  ## What was done?
  Allow re-signing specifically for EHF messages, this is important as due to rotation, and duplicate requestIDs a member will refuse to re-sign when they participate in a later quorum.

  ## How Has This Been Tested?
  Devnet deployed with a mix of this version, older versions and current v21.0

  ## Breaking Changes
  This doesn't introduce any breaking changes
