feat(ivy): require 'token' for ngInjectableDef (#30855)

The compiler generates a 'token' field when it emits an ngInjectableDef,
but this field was not required by defineInjectable or the InjectableDef
interface, nor was it added by InjectionToken.

This commit makes 'token' required and adds it where missing.
