Stop creating TKG content source related resources.

This change stops watching TKG content source in the provider configmap
and creating/updating/deleting related resources, such as ContentLibraryProvider and ContentSourceBindings when WCP_VM_Image_Registry FSS is enabled.

Test done:
- make test
- make test-integration
- manually deployed to a WCP cluster
  - passed internal gce2e tests
  - no TKG related ContentSource/ContentSourceBindings are created.
