refactor(ivy): do not generate providedIn: null (#34116) 

We should only generate the `providedIn` property in injectable
defs if it has a non-null value. `null` does not communicate
any information to the runtime that isn't communicated already
by the absence of the property.

This should give us some modest code size savings.
