[Developer Tools] Visual Studio 2019 Lifecycle update

[FLY1NGSQU1RR3L]

Issue
Visual Studio 2019 version 16.4 is out of support as of October 2021.

Workaround
Please move to Visual Studio 2019 version 16.7, 16.9, or 16.11 for continued servicing and support. A future GDK release will generate a build error with Visual Studio 2019 version 16.0–16.6—the GDK currently generates a build error if versions 16.0–16.3 are in use.

Note: The GDK continues to support using Visual Studio 2017 version 15.9.
