Fix typeforward resolutions

[KevinRansom]

Numerics Type Forwards were being set with the version number of the fsharp.core dll. 4.1.0.0

This ensures that they are set to the version number of the referenced system.numerics or system.runtime.numerics dll depending on whether it's full framework or portable/coreclr build.
