Disable generation of resolvers, but keep inputs, args & models.

**Is your feature request related to a problem? Please describe.**
I rarely use the generated resolvers as I usually have some business logic associated with each action (send emails etc), so generating all the resolvers is not required for me and probably takes up extra time when generating them.

**Describe the solution you'd like**
Some option to disable generating the resolvers.
I still require the inputs, args and models to be generated.

**Describe alternatives you've considered**
Can't do anything now I dont think?

Start by locating the Prisma generator entry point and the code paths that emit resolvers, inputs, args, and models. Check how generator options are defined and exercised, then verify that the chosen option omits resolvers while retaining the other generated outputs.
