Update to Visual Studio 16.10

[traversaro]

Fixes https://github.com/conda-forge/vc-feedstock/issues/36 .

It is the first time I do this, so it is possible I am doing something wrong. @isuruf do you think it make sense to remove the 16.8 combination from conda_build_config.yaml?

Hi! This is the friendly automated conda-forge-linting service.

I just wanted to let you know that I linted all conda-recipes in your PR (recipe) and found it was in an excellent condition.

I do have some suggestions for making it better though...

For recipe:

• It looks like the 'vc' output doesn't have any tests.
• It looks like the 'vs_linux-64' output doesn't have any tests.

It seems that the script is not able to extract some .dll, probably something changed in the sctructure of the redist installer.

By looking in my system, indeed in the Visual Studio install in C:\Program Files (x86)\Microsoft Visual Studio\2019\Enterprise\VC\Redist\MSVC\14.29.30036\x64\Microsoft.VC142.CRT the only files there are:

api-ms-core-* are part of UCRT and was shipped with earlier versions of vcredist and it seems that microsoft has dropped them. This is part of the OS for windows 10, but is not for windows 8. See https://docs.microsoft.com/en-us/cpp/porting/upgrade-your-code-to-the-universal-crt?view=msvc-160#deployment-and-redistribution-of-the-universal-crt

Not sure what to do here. cc @conda-forge/core.

Can we ship them as a separate package for Windows 8 users (if we can get them from somewhere) and just drop them from the default vc package?

[isuruf]

We can get them from windows sdk ISO.
