Update AggregateAndProof and rename slot_signature to get_slot_signature
1. Reorder the fields to fit the container name
2. Rename `AggregateAndProof.index: ValidatorIndex` to `AggregateAndProof.aggregator_index: ValidatorIndex`
    - Since we also have similar naming style like
`ProposerSlashing.proposer_index` or `VoluntaryExit.validator_index`
