VS: Suppress MSBuild default settings affected by UseDebugLibraries

`Microsoft.Cl.Common.props` changes some default settings based on
`UseDebugLibraries`.  CMake models its own controls for these settings,
so if the project does not set them, explicitly suppress them to avoid
letting `UseDebugLibraries` affect them.
