[VMR] Ensure the VMR builds and publishes all of Roslyn

[dibarbet]

Currently the VMR may not build all of Roslyn. In order to publish from the VMR all of Roslyn must be built and packed. Packages should go to the correct intermediate feeds, and IsShipping packages should go to nuget.org

Roslyn packages must be updated to include the correct IsShipping flag for any that go to nuget.rog.
