    NMake Makefiles: Apply toolset version for Meson-built deps
    
    As the Meson build files for Visual Studio apply the toolset version in the
    .lib filenames by default, apply the toolset version in the Meson-built -mm
    .lib files that we link in, just as we did when we we link in the -mm .lib
    files that was built with NMake, by default.
    
    The option 'USE_COMPAT_LIBS' will also mean that we will use the former
    behavior when we link in the Meson-built -mm .lib's, just as we did when we
    link in the NMake-built -mm .lib's.
    
    Also fix the case also when the 'USE_COMPAT_LIBS' option is used and when
    'USE_MESON_LIBS' is not used on Visual Studio 2017, where the toolset version
    was not correctly applied.
