Poor error message from IL2CPP on Windows Desktop with specific Visual Studio installation sequence

Windows

-

I'm submitting this bug report on behalf of a user who posted about it on the forum here: https://forum.unity.com/threads/il2cpp-build-problem.994606/#post-6458698

I've not reproduced it locally, but it seems these are the Visual Studio installation steps, as described by the user:

* had VS2017, uninstalled it
* installed VS2019
* added some .NET versions
* added Unity Hub

Then when the user builds an IL2CPP player, they get a rather cryptic error message from the Microsoft C++ compiler:

Cannot open include file: 'string.h': No such file or directory

Likely, the issue is that the C++ workload for Visual Studio is not installed. However, Unity or IL2CPP should be able to detect this case and provide a better error message.
