[ska] relocate oblt deployment-agnostic api integration tests (elastic#227194)

## Summary

Part of elastic/kibana-team#1503

This PR is mostly about moving **observability deployment-agnostic
tests** from x-pack/test

```
x-pack/test/api_integration/deployment_agnostic/
     | - observability/apis/
     | - configs/
     | - feature_flag_configs/
```

After: 
```
x-pack/solutions/observability/test/api_integration_deployment_agnostic/
     | - apis/
     | - configs/
     | - feature_flag_configs/
```

Notes:
- some services like `alertingApi` and `observabilityAIAssistantApi`
were left as copies in original path as other oblt tests depend on them
and we try to avoid circular dependencies caused by importing from
solution test dirs.
