Template engine tests hitting known parallelism issue in GetVisualStudioInstances

Is there an issue describing the problem? Are there people working on fixing it? We're hitting this in the aspnetcore repo a lot and as far as I'm aware we don't do anything with UWP which is how the sdk resolved the problem.

@jaredpar sent a PR here with a short-term workaround that we're working to merge: #44930

The 'true' fix is coming in a future VS release, there was some unintended concurrent access to a critical section that wasn't locked.
