In past versions of the View Engine compiler, we added a warning that is
printed whenever the compiler comes across an Angular declaration with a
constructor that does not match suitable DI tokens. The warning mentioned
that in `v6.x` it will turn into an actual error.
This actually happened as expected for most cases. e.g. the constructor
of `@NgModule`, `@Component`'s, `@Pipe`'s etc will be checked and an error
will be reported if constructor is not DI compatible.
The warning has never been removed though as it was still relevant for
unprovided injectables, or injectables serialized into summaries of the
Angular compiler.
As of version 10, classes that use Angular features need an Angular decorator.
This includes base classes of services that use the lifecycles Angular feature.
Due to this being a common pattern now, we can remove the warning in
View Engine. The warning is not correct, and also quite confusing as it
mentions the planned removal in `v6.x`.
Resolves FW-2147.
