[java-interop] Update to SDK style project (#657)

Update `java-interop.csproj` to be an SDK-style style. This is a bit tricky because this is not a C# assembly, it is just hijacking a `.csproj` and overriding some targets to build a C lib. It felt cleaner to go with a more "supported" version of doing this, so the project is built on [Microsoft.Build.NoTargets][0], which is designed to run arbitrary commands without building an assembly. Also switches to a stable Mono. Not sure if this is necessary but the more modern the `MSBuild` support when working with SDK style projects, the better. The automatic downloading of the `NoTargets` package didn't work with our `globalPackagesFolder` set to `$\..\packages`, so that was changed to `packages`, which is what XA uses and it works.
