Subject: [PATCH] VS: Pass platform when invoking MSBuild

MSBuild expects a `/p:Platform=...` argument to tell it which platform
to build among those in the `.vcxproj` files.  We have not historically
had to do this because we generate only one platform.  However, when
a project uses `include_external_msproject` the included project file
may have other platforms.

Fixes: #18308
