feat: Add graphql.scalar() utility to check/retrieve scalar/enum types

[kitten]

Resolves #44

Summary

This adds a new identity method on graphql.scalar() that can either be used to retrieve or type check the type of scalars and enums.

To retrieve the type of a scalar it's used with typeof:

type testEnum = ReturnType<typeof graphql.scalar<'test'>>;

To check the type of a scalar it's used by calling it:

const test = graphql.scalar('test', 'more');
