Jon Häggblad 66931028f4 Don't repeatedly lookup keys in babe_epochAuthorship rpc function (#5962) ...

* babe: don't repeatedly lookup keys in authorship rpc function

Expose a new function `claim_slot_using_keypars` in Babe so that the `babe_epochAuthorship` can
lookup authorship for all slots in the epoch without repeatedly looking up keys in the keystore.

Time to run the `babe_epochAuthorship` RPC call goes from 7s to 25ms on a local dev chain on my
machine.

* babe: pass reference to slice instead of ref to Vec

* babe: fix bunch of clippy warnings
