This updates the message report for non-exhaustive switch statements and expressions to include the witness in the problem message and a reduced witness, which doesn't include properties that fully cover the static type. The message is also split into two messages; one for switch statements and one for switch expressions, allowing for a better wording regarding the default/wildcard pattern case.
