There can still be errors while uploading files to blob storage, even after confirming that the file doesn't already exist at the given location. See: https://dev.azure.com/dnceng/internal/_build/results?buildId=1443383&view=logs&j=8667c75e-c9c8-5a72-3326-7d35d151733c&t=648bbdf3-1356-5b63-95ae-560e1b5f90bf. Today, that exception is thrown, but since everything is async, it isn't clear what package was having an issue publishing.

This change adds a try/catch around the call to UploadAsync, and will long the file name and blob path along with the exception message if UploadAsync throws an exception.

Instead of relying on the work item to request retry/reboot, we do it in the SDK at the end of the job while reading the `diagnostics.json` file generated by XHarness.
This will transparently work for any number of XHarness commands executed during the work item and can be a single place for the logic. It also unifies the logic we had duplicated over the `.ps` and `.sh` files.
The user then doesn't need to categorize or react on failed XHarness commands in any way.

We still allow the users to request retry/reboot using the .dotfiles but it should not be necessary.

[main] Update dependencies from dotnet/roslyn

[main] Update dependencies from dotnet/xharness dotnet/arcade

In repos that need to mix vs and dotnet msbuild engines, and use this script directly, we need to allow for the msbuildEngine to be passed in.

* Add missing MicrosoftSourceLinkVersion property definition

* Update Versions.props

The path was actually needlessly long which could cause problems with the `dotnet tool install` command

The name of the package was repeated twice for no reason:

… 4.7.2, to allow usage from desktop msbuild. (#8158)
