Compare files from source generators

[vsfeedback]

This issue has been moved from a ticket on Developer Community.

The new compare files feature could be useful to compare the output of a roslyn source generator with other files, either in the solution or somewhere else. E.g. when creating a source generator I would like to be able to compare the current output of my generator with a prepared file of the expected output. At the moment this only works on actual physical files.
