Which @angular/* package(s) are relevant/related to the feature request?

localize

Description

In angular/angular-cli#24145 (comment), we discovered that the compiler expects $localize to be used as global, not imported from @angular/localize/init. This is confusing and leads to users misusing the function.

Proposed solution

We should remove the exported $localize from this package and instead let users depend on it via the global declaration.
