Cleaning up the cluster interface by moving almost all related declar… (#9080)

* Cleaning up the cluster interface by moving almost all related declarations into cluster.h
(no logic change -- just moving declarations/definitions around)

This initial effort leaves two items out of scope - the configuration parsing into the server
struct and the internals exposed by the clusterNode struct.

* Remove unneeded declarations of dictSds*
Ideally all the dictSds functionality would move from server.c into a dedicated module
so we can avoid the duplication in redis-benchmark/cli

* Move crc16 back into server.h, will be moved out once we create a seperate header file for
hashing functions
