Reduce the number of workflows in CI

[JirkaAichler]

Is your feature request related to a problem? Please describe. The number of workflows is growing. Reducing their number could increase the stability, speed, and maintainability of the pipeline.

Describe the solution you'd like The main workflow would have all features enabled and the majority of the tests would run against it. The additional workflows would be used only when a different configuration is required.

Example: I would like to test a new security feature that is using all authentication schemes. Client certificates, access tokens, and OIDC have a separate workflows so I can't reuse any existing workflow.
