Remove unreferenced components when filter is applied

[timofei-iatsenko]

Description

Our api services exposes different endpoints to separate users traffic:

/public
/internal

They all described in one OpenAPi schema, since they are served from one microservice.

The endpoints on these prefixes are consumed by completely different application.

I want to generate types and sdks only for the /public prefixed endpoints. I was able to achieve that, but generator still generate all component types for all entities used in /internal endpoint.

What i want is to have a reference count feature for components in OpenApi schema, and if it's not used anywhere it will not be generated.

Currently this is very hard to achieve using exclude/include feature, because you need to list all type names one by one.
