Rename registerServiceWithCallback

Rename registerServiceWithCallback to registerService. User cannot pass
a callback to registerServiceWithCallback, so its name is confusing.
Rename it to registerService. Because it is part of
LazyServiceRegistrar, it should be clear what this function does.

Test: Build and check that cas functions as a lazy hal as before
