MSVC: Disable conformance check that breaks with default WinSDK

Browse Source 
The default Windows SDK installed for VC++ 2022 is 10.0.19041, and still
has the issue described here, breaking builds if -Zcpreprocessor is set:

https://developercommunity.visualstudio.com/t/stdc17-generates-warning-compiling-windowsh/1249671

The issue might be fixed in SDK version 2104 (10.0.20348.0), but until
that is the default SDK when installing the compiler, turn that
conformance check off again.

Partially reverts commit 8cb832090a
