windows builds: devenv freetype /update appears not to have an effect

Despite attempting to upgrade the freetype sln file with /upgrade, when building using the 2017 msbuild as part of setup.py I get the following failure:

Making the following change appears to fix the issue for me on 3.8:

but I'm not sure how ideal hard-coding v140 is. It's better than falling back on v100 at least...

We may be able to reuse https://github.com/python/cpython/blob/9baf242fc733ab8a52a0b6201d95c6fdb8251745/PCbuild/python.props#L7-L21? (by patching the relevant file in the freetype build script)

@eric-wieser could you please check if #16401 fixes the issue?

Yes, that seemed to do the trick
