Embedded source files

[ViktorHofer]

There is the option in roslyn to embed source files directly into the pdb. Is support plan to handle such scenarios? In corefx we are missing source files from System.Private.CoreLib which is located in another repository (coreclr). If we would embed the sources directly into the pdb we could mitigate this issue but that requires support from both coverlet and ReportGenerator.

Closing as it seems not work needs to be done here in favor of SourceLink: https://github.com/dotnet/corefx/issues/30974#issuecomment-443273154
