Remove PackageTargetFramework

This property is largely obsolete and replaced with NuGetTargetMoniker
where its needed.

I've also cleaned up mentions of this and validation suppression around
it in projects that will never be packaged.

PackageTargetFramework remains in projects that will be packaged and
duplicate their asset in multiple folders,
eg: netstandard1.0;portable-net45+win8+wp8+wpa81
