OASFilter is called twice

[Postremus]

Describe the bug
I have a custom OASFilter. It gets executed twice, which can be easily seen in the ui.

Expected behavior
Each filter should only be executed once for a openapi document.

Actual behavior
Filter is executed twice.

To Reproduce

Steps to reproduce the behavior:

1. Download the reproducer:
   duplicate-oas-filter.zip

2. mvn quarkus:dev

3. go to localhost:8080/swagger-ui

4. "First Filter!" is output twice on the "/hello-resteasy" operation.

Thanks @Postremus - I am looking at this now.

What happend here is that we moved the filter to runtime, to allow people to do dynamic filtering based on runtime config, but never removed the compile time filter, so the filter now gets called twice. #13715 fixes that.
