[Feature Request] Fix OpenAPI documentation generator crash for RPC endpoints

[daaain]

Is your feature request related to a problem? Please describe. Currently for RPC endpoints the OpenAPI plugin generates a massive JSON file (100K+ lines for ~20 models), which makes the browser stall when using Swagger UI and trying to expand an API definition (eventually a popup asks to stop the script) and crash Redocly CLI with FATAL ERROR: Reached heap limit Allocation failed - JavaScript heap out of memory.

Describe the solution you'd like A way to configure the depth the types that are generated by the OpenAPI plugin to put a limit on the size of each endpoint's schema.

Describe alternatives you've considered I guess the documentation generators could also prevent this issue on their side.
