Investigate Edit-and-Continue vs. PIA Embed-Interop-Types

I think edit-and-continue does not work for methods that use an embed-interop-types COM class.
That means if we disable embed-interop-types we have a much better edit-and-continue experience.

We should check and document this if true. (also https://github.com/dotnet/roslyn/wiki/EnC-Supported-Edits)

We might try to figure out if we can disable the options for debug builds only. That might be a suitable default if not too disruptive.
