SE-0200: "Raw" mode string literals

I’ll concede I no longer stand behind syntax mentioned in the proposal as written and I auto-reject it if such a thing is possible.

There is an already existing “pitch phase” thread we could use rather than create another one: [Pitch] Raw mode string literals. I think we should keep this proposal thread open though and discuss syntax here as it has been far more focused than the pitch thread which went off on all sorts of tangents and was not conclusive.

Can we laser focus on what the syntax should be please and enumerate use cases and I can update the proposal for resubmission hopefully with someone who is a better writer of English than I is.
