[#42] Share Vote/RemoteVotes between contracts
Replace vote/remoteVotes functions from all contracts (except alphabet) to common package. Additionally replace setSerialized and bytesEqual. Create InitVote function and use it in NeoFS and Netmap contracts. Signed-off-by: Leonard Lyubich <leonard@nspcc.ru>
