      Prepare to import project extensions which usually come from packages.  Package management systems will create a file at:
          $(MSBuildProjectExtensionsPath)\$(MSBuildProjectFile).<SomethingUnique>.targets

        Each package management system should use a unique moniker to avoid collisions.  It is a wild-card import so the package
        management system can write out multiple files but the order of the import is alphabetic because MSBuild sorts the list.

        Don't import project extensions during restore because NuGet restore generates them.  Importing them during restore will embed
        the pre-restore files in the binary log and then NuGet won't be able to embed the generated one after restore.  If some other
        project extension mechanism wants to import project extensions during restore, they need to explicitly set ImportProjectExtensionTargets
