This pr intends to support both proposals metioned in RFC.

Proposal A: "Array of SWRs"

API

const { result } = useSWRList(keys, fetcher, config)

interface Result {
    data: any;
    error: any;
    mutate: KeyedMutator<any>;
    isValidating: boolean;
    isLoading: boolean;
    key: string;
    originKey: Arguments;
}

Proposal B: Aggregated Return

API

const { data, isLoading, isValidating, mutate } = useSWRList(keys, fetcher, config)

type Data = {
    data?: any;
    error?: any;
    key: string;
    originKey: Arguments;
}[]
