@1.2::IServiceManager: remove 'removeService' todo

Thinking about this in more detail, if a service is removed, there are
two problems:
- lazy HAL mechanism doesn't support adding the service back.
- ownership may have already been passed to other clients.

For these reasons, for the time being, we can't add this API.
