Backport compiler option "-Ydebug-error" from scala 3

[tribbloid]

This is a very important option when working with a fast-moving compiler or unstable compiler plugin. Yet it is missing in scala 2 for a very long time. (The option "-Yissue-debug" only covers a very small subsection of errors that can be handled by "-Ydebug-error")

To me it looks like a low-hanging fruit, time to bring it up to be on par with Scala 3.

I'm closing this ticket because this issue tracker is for bugs. This doesn't mean I disagree with the idea; but we are not collecting feature requests / ideas here.
