test: improve mine rotation quorums for IS in functional tests

[knst]

Issue being fixed or feature implemented

Mining rotation quorum currently is not trivial. All over a codebase used this template to get a rotating quorum:

        self.move_to_next_cycle()
        self.log.info("Cycle H height:" + str(self.nodes[0].getblockcount()))
        self.move_to_next_cycle()
        self.log.info("Cycle H+C height:" + str(self.nodes[0].getblockcount()))
        self.move_to_next_cycle()
        self.log.info("Cycle H+2C height:" + str(self.nodes[0].getblockcount()))

        self.mine_cycle_quorum(llmq_type_name='llmq_test_dip0024', llmq_type=103)

The performance of this code is not great also because generating 3 or 4 batches of blocks requires time to sync nodes after each batch.

What was done?

This PR move instantly to 3-4 DKG sessions forward and starts from cycling quorum.
It's only one cycling quorum (instant-send), so, extra params are also removed.
To get it just call:

self.mine_cycle_quorum() # first time, which is usually used to get IS feature working in functional tests
self.mine_cycle_quorum(is_first=False) # if you don't need preparing 3 DKG sessions in advance

How Has This Been Tested?

Run unit and functional tests
By my benchmark it gives roughly 10 seconds for each functional test that uses rotation quorum.

utACK f8cfda6; I wish that is_first could be automatically detected instead of manually set.
