Support for uploading iOS, tvOS and watchOS Apps to iTunes Connect

Starting with Xcode 11, Apple stopped distributing Application Loader, which was used to publish Apps to the iTunes Connect website.

We updated our MSBuild tasks to make use of a new tool shipped with Xcode: altool.

This is a necessary step for the IDEs to continue providing the ability to publish Apps to the App Store.
