  Log Message:
  -----------
  [ADT] Add `DefaultUnreachable("msg")` to StringSwitch (#161976)

Similar to TypeSwitch (#161970), allow for explicit unreachable default
case with a custom error message on unhandled cases.

StringSwitch already allowed for checking if any of the cases matched
with the conversion operator, but `DefaultUnreachable` is more explicit
and allows for a custom message.
