Add defineRules function

[Shinigami92]

This idea came into my mind by chatting with @antfu 🚀

It is a helper function to shorten the configs a bit by reducing the redundant and sometimes long names by mapping over the rules

defineRules('@typescript-eslint', {
  'array-type': [
    'error',
    { default: 'array-simple', readonly: 'generic' },
  ],
  'consistent-type-imports': 'error',
});

Additionally due to we now provide the specific plugin name, we can ensure that the types are exactly from that plugin and throw a compile time error if the rule e.g. has a typo and does not exists

Also the rules are grouped indirectly together by this, which is also a nice thing

We can use

type RemovePrefix<TPrefix extends string, TString extends string>
  = TString extends `${TPrefix}${infer T}`
  ? T
  : never

@antfu right now I just got something like this to work: https://github.com/Shinigami92/eslint-define-config/blob/define-rules-fn/src/define-rules.ts

I have to many TypeScript problems when I try to bring them together into just one function and use generics. 🤕

These explicit functions would work, but they would have the problem that they won't really work anymore,
when we would try to rebuild eslint-define-config with using augmented global properties 🤔

Do you think you can help me a bit with that?

I think due to the augmented global properties support, this feels obsolete
