Add regression tests for duplicate class property names

Check that a class property cannot share a name with another property, a
function, a task, a parameter, a type, or an enum named constant. Check
duplicate properties in both separate and comma-separated declarations. The
latter guards the shared declaration type ownership that previously caused a
crash.

Exercise properties in both declaration orders so both member registration
paths are covered.
