Disabled Serverless add actions should not be displayed in topology menu

Description of problem:
This is a follow-up on OCPBUGS-2579, where Prabhu fixed a similar issue for catalog items "Helm Charts" and "Samples". The same issue happens also for Serverless actions "Event Sink", "Event Source", "Channel" and "Broken".

Version-Release number of selected component (if applicable):
4.13, earlier versions have the same issue

How reproducible:
Always

Steps to Reproduce:
1. Install Serverless operator and create Eventing and Serving resources
2. Import an application (Developer perspective > add > container image)
3. Open customization (path /cluster-configuration/) and disable all add actions
4. Wait some seconds and check that the Developer perspective > Add page shows no items
5. Navigate to topology perspective and right click outside of the app / workload

Actual results:
Add to project menu is shown with the options "Event Sink", "Event Source", "Channel" and "Broken".

Expected results:
The options "Event Sink", "Event Source", "Channel" and "Broken" should not be shown when they are disabled.
