[Proposal] Extend TypeName to other types

[Sytten]

I would like to propose an upgrade to the typing system.
Currently when creating plugins you have to limit the generics to extends string if you want to be able to access values using RootValue for example. It would be great to be able to use NexusObjectTypeDef instead. Here is an example from the plugin I am currently working on:

const myRule = ruleType({
  type: Test, // Not possible since NexusObjectTypeDef<'Test'> is no assignable to 'Test'
  resolve: (_root, _args, _ctx, _info) => {
    return true;
  },
});

export const Test = objectType({
  name: 'Test',
  definition(t) {
    t.id('id');
    t.string('prop');
    t.field('test', {
      type: EnumTest,
      shield: myRule,
      resolve(_root) {
        return 'test';
      },
    });
  },
});
