Retry tests if msbuild crashes

[radical]

And get the msbuild debug files from crashes to aid debugging.

Issue: #6163

Microsoft Reviewers: Open in CodeFlow

Do we understand why the crash is happening though? How confident are we that when in a failure state, retrying will make this pass?

[radical]

It doesn't crash like this on every build, but it does crash sometimes. So, this is just to ease the pain of having to do retries or having red builds on internal pipeline. Meanwhile, we are tracking the occurrence of these with #6163 .

@joperezr I think this would be useful to take.

LGTM, thanks @radical. If there is a way of not only retrying, but also keeping trace of when that needed to happen it would be great, as that way we won't get false-negatives indicating that this is no longer a problem, but that shouldn't block this.

I'm setting MSBUILDDEBUGPATH here, so we should get some debug logs from msbuild which we can use to further debug this.
