Vadim Zeitlin 271711b030 Get rid of spurious warning in CRT malloc.h with MSVS 2017
Recent MSVS 2017 versions (15.9.x) as well as MSVS 2019 give warning
C4548 about "expression before comma having no effect" when including
standard CRT headers.

This happens because when building projects targeting 8.1 SDK, as the
IDE uses the hard coded 10.0.240.0 version of UCRT headers in this case
(see \Common7\IDE\VC\VCTargets\Microsoft.Cpp.Common.props), and the
headers in this version haven't been, and will never be, updated to
avoid this warning, as was done in later 10.0.x UCRT versions.

Fix this by explicitly disabling the warning in wx/beforestd.h, as even
setting the warning level to 1 for the standard headers somehow isn't
enough to suppress it if it's enabled.
