[_fe_analyzer_shared] Update non-exhaustive message
...
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.
