Introduce requireRootResolvers in GraphQL Modules preset

[kamilkisiela]

type Query {
  hi(msg: String): Message!
}

type Message {
  body: String!
}

Before (and current default)

import { MyModule } from './generated';
export const resolvers: MyModule.Resolvers = {}; // <-- totally fine

With requireRootResolvers enabled:

import { MyModule } from './generated';
export const resolvers: MyModule.Resolvers = {}; // <-- Oopsie, `Query` and `Query.hi` are missing

It could help people to make sure all resolvers are defined (I think we enforce root-level resolvers in GraphQL Modules library as part of runtime check)
