Adds two new helper functions that can be used when unit testing Angular services that depend upon upgraded AngularJS services, or vice versa. The functions return a module (AngularJS or NgModule) that is configured to wire up the Angular and AngularJS injectors without the need to actually bootstrap a full hybrid application. This makes it simpler and faster to unit test services. PR Close #16848
