Remove IDynamicRegistrationProvider from CohostWrapWithTagEndpoint

Removed unnecessary dynamic registration implementation as WrapWithTag doesn't need registration:
- Removed IDynamicRegistrationProvider interface implementation
- Removed Export attribute for IDynamicRegistrationProvider
- Removed GetRegistrations method
