[RFR] Add useListController hook

[fzaninotto]

It helps remove one level in the component tree for lists, and makes the return type explicit. Also, it's easier to understand.

import {useListController } from 'react-admin';
import ListView from './ListView';

const MyList = props => {
    const controllerProps = useListController(props);
    return <ListView {...controllerProps} {...props} />;
}

The ListController component remains for backward compatibility, and to be able to test useListController.

There will be more such controllers (useEditController, etc) but Rome wasn't built in one day.
