build: Fix MSVC /Zc:preprocessor warning (#1461)

Don't add the /Zc:preprocessor- compiler flag when it's not needed, to
avoid the following warning:
D9025 : overriding '/Zc:preprocessor' with '/Zc:preprocessor-

The latest Windows SDK v10.0.22621 compiles fine with conforming
preprocessor enabled, the bug was in older SDK-s like <=10.0.20348.0.

Add the /Zc:preprocessor for msvc >=v19.25, it didn't exist before this
version (it existed as /experimental:preprocessor before).
