Improve CDDL specs by using any

[coot]

CDDL has the notion of any which can be used to indicate that something is not specified. We provided this for Tx and TxId in tx-submission mini-protocol in #4580. It would be nide to extend this approach to other mini-protocols.

• chain-sync Use any in cddl specs / tests. #4638
• block-fetch Use any in cddl specs / tests. #4638
• tx-submission Fixed cddl spec for tx-submission protocol #4580
• local-tx-submission
• local-state-query
• local-tx-monitor Use any in cddl specs / tests. #4638
• node-to-client-handshake (a non polymorphic protocol)
• node-to-node-handshake (a non polymorphic protocol)
• peer-sharing (polymorphic over peeraddr, which is instantiated to SockAddr)
• keep-alive (a non polymorphic protocol)

I took a look into this. And the rest of the protocols use ouroboros-network-mock and ouroboros-network-api mock types for Point, Block, etc.. types. I am not sure we want to stop using these since they belong to the testing ecosystem and mock the real thing.

For example SlotNo could be Any but we are using a type that comes from cardano-slotting and changing it to Any would be a lot of effort
