https://devdiv.visualstudio.com/DevDiv/_git/VS/pullrequest/584809 is removing Microsoft.Build.Engine references and replaces them with Microsoft.Build (as that was transitively brought beforte and code could took indirectly dependency on it).
We could have tried to remove in single shot - but it'd increase breaking possibility. So let's first do the replacement and then in second step attempt to remove Microsoft.Build dependencies which seem dead.
