Cannot specify platform for modern cmake msvs generator

QtCreator forms incorrect generator string. Ok, it's correct for msvs 2017 generator, but not for msvs 2019 generator.

For example, 

Here QtCreator creates string

 "-GVisual Studio 16 2019 -A Win32"

but it's incorrect for msvs 2019.

Generators
* Visual Studio 16 2019 = Generates Visual Studio 2019 project files.
Use -A option to specify architecture.
Visual Studio 15 2017 [arch] = Generates Visual Studio 2017 project files.
Optional [arch] can be "Win64" or "ARM".

QtCreator should create string

 -G "Visual Studio 16 2019" -A "Win32"

for msvs 2019+
