experiment: additional arguments into `selectState`

As requested by Daniel in chat.

It's not a lot of code, so it could be discussion-worthy.

Essentially, the idea is to be able to pass additional args into the selectors created by the entityAdapter. Actually, this is currently already possible for everything except selectById due to how reselect works - but not supported by the types.

Example:

import { createEntityAdapter } from "@reduxjs/toolkit";

const adapter = createEntityAdapter();

export const { selectAll: getComponents } = adapter.getSelectors(
  // @ts-ignore
  (state, containerId) => state.page.containers[containerId].components
);

let components = adapter.getInitialState();
components = adapter.addOne(components, { id: 1, foo: "bar" });

const state = {
    page: {
      containers: [undefined, undefined, { components }]
    }
  };

//@ts-ignore
const x = getComponents(state, 2);
