feat: add GovernorVotesSuperQuorumFraction extension

[tasin2610]

This PR implements the GovernorVotesSuperQuorumFraction extension as requested in issue #1386.

Fixes #1386.

Description

This extension enhances the governance system by introducing a "super quorum" threshold. When a proposal receives votes exceeding this threshold (and has a majority of "for" votes), it can be moved to the Succeeded state before the standard voting period ends. This allows for faster governance decisions when there is overwhelming support.

The extension:

• Builds on top of GovernorVotesQuorumFraction
• Stores a super quorum numerator that must be greater than the regular quorum numerator
• Provides methods to check if a proposal has reached super quorum

Implementation details

• Added GovernorVotesSuperQuorumFractionComponent with storage for tracking super quorum numerator history
• Implemented ISuperQuorumFraction interface
• Added has_reached_super_quorum utility method
• Properly integrated with existing governor architecture

Requirements

• Super quorum must be greater than regular quorum
• Super quorum must not exceed the denominator
• Includes proper validation and error messages

PR Checklist

• Tests
• Documentation
• Added entry to CHANGELOG.md
• Tried the feature on a public network
