Introduces an update schematic for the "@angular/core" package that automatically migrates pre-V8 "ViewChild" and "ContentChild" queries to the new explicit timing syntax. This is not required yet, but with Ivy, queries will be "dynamic" by default. Therefore specifying an explicit query timing ensures that developers can smoothly migrate to Ivy (once it's the default). Read more about the explicit timing API here: https://github.com/angular/angular/pull/28810 PR Close #28983
