3.2 C#: Upgrade GodotTools to nuget Microsoft.Build

This upgrade is needed in order to support
reading and editing project files that use Sdks
as well as other new features. A common example
in 3.2 is having to specify a PackageReference
version with a child element rather than the
attribute. This is no longer the case now.
