feat!: calculate quorum members using v20 cbtx clsig (#5366)
## Issue being fixed or feature implemented

Implementation of Randomness Beacon Part 2.
This PR is the next step of #5262.

Starting from v20 activation fork, members for quorums are sorted using
(if available) the best CL signature found in Coinbase.
If no CL signature is present yet, then the usual way is used (By using
Blockhash instead)

## What was done?

## How Has This Been Tested?
Test `feature_llmq_rotation.py` was updated to cover both rotated and
non-rotated quorums.
2 quorums are mined first to ensure Chainlock are working earlier.
Then dip_24 activation is replaced by v20 activation.

The only direct way to test this change is to make sure that all
expected quorums after v20 activation are properly formed.

Note: A `wait_for_chainlocked_block_all_nodes` is called between every
rotation cycle to ensure that Coinbase will use a different Chainlock
signature.

## Breaking Changes
Yes, quorum members will be calculated differently.
