Use TaskStatusCenter instead of IVsStatusBar for restore progress reporting in VS

[nkolev92]

This API will work the same in both VS & VS.Oe scenarios.

Internal issue was closed as not repro. Possible it was fixed by other related efforts since the original filing of the issue.

We should validate that it's actually correct.

We should try not having a task status center for on build and explicit restore, but have one only for solution load.

Another option is to start the restore, and if it takes more than x time (0.5 seconds? 1 second?) to add the task status center item. That way quick restores don't cause a popup, but longer restores do (whether it's solution load, git branch change, manually editing a csproj).

The API is a bit of a nightmare :D It requires you to pass it a task and it basically tracks completion based on the task returning.

Also right now PC and PR restores are completely separate, 2 different progress reportings, so we'd need to combine that somehow, so require some refactoring there.
