[Tests] Replace azurestorage with a github repo. (dotnet#7524)

Our `https://xamjenkinsartifact.azureedge.net` site for some of the
unit test data seems to have disappeared.

So lets use a github repo to store this data instead. The unit tests
can download the raw files directly from github. The repo will be
public as well so there won't be any need for authorization.

Update `DeleteBinObjTest` to use `7z`
