[Chapel Merge] Add two tests to lock in the failure mode describe

Branch: refs/heads/main
Revision: 94fd7df

Log Message:

Merge pull request #18555 from lydia-duncan/addSuperFutures

Add two tests to lock in the failure mode described by #8069
[new tests, discussed on the original issue, not reviewed]

These tests access super in a context where it seems like we should not be
allowed to reference it - one outside the body of the class, and one when inside
a method on the class but on another instance of it.

Checked a fresh checkout of the tests.
