Increase CrudResolvers granularity (only queries, mutations, etc.)

Is there an easy way to import all crudResolvers of a certain type for all models without having to import them individually each model? If not, can we add that as a new feature?

For example, I want to import all crudResolvers that are only queries (findOne, findMany, findUnique, etc.) for all of my models, but I want to exclude mutations (create, update, upsert, delete). I also want to import them for all of my models in one object, like with `crudResolvers`, and not have to import them individually for each model. That way if I add more models later to my schema, I don't have to worry about updating my imports as well.

Right now, I don't see an easy way to do this. I've tried some hacky solutions like deleting the mutation resolver methods from the `crudResolvers` prototype object, but the decorator metadata still remains so they still show up in the graphQL schema (though the functionality no longer works). Maybe a dynamic import solution would work, but that can get messy.

Can we add this in as a feature? Maybe it could be similar to how the `emitOnly` field works in the generator--we could specify to emit only queries, mutations, or specific crud operations. Let me know what you think.

Thanks!

Start by tracing how `crudResolvers` are assembled and how the generator's `emitOnly` option selects operations. Define how a single aggregate of query-only, mutation-only, or selected CRUD resolvers should be exposed for all models, including how newly generated models are included; done means the resulting GraphQL schema contains only the requested operations without individual model imports.
