Onboard to source.dot.net

See: https://github.com/dotnet/core-eng/issues/15641

There is a .yaml template we could use to get the sources for Microsoft.iOS.dll, etc. up on https://source.dot.net/.

It looks like we would probably also need a variable group setup in devdiv's AzDO instance.

Does source.dot.net support generated sources, or must all source code be checked in?

I think you give it a .binlog and it finds all the source files and zips them up:
