Remove with-parent-controls developmental feature (#1819)

* Revert changes from usnistgov/OSCAL#1717 that address a documented feature in the profile resolution spec that didn't exist in the model. Instead of updating the model, this PR removes the "with-parent-controls" feature from the profile resolution spec.

This developmental feature should be removed for the following reasons.
- This feature is not implemented in any of the current XSLT or Java implementations.
- This feature is not being requested from a significant segment of the user community. The related issue usnistgov/OSCAL#1662 has support from 1 community member outside the NIST team.
- This feature is extremely difficult to implement along with with-child-controls, which works on the opposite axis.
- IMHO, profile resolution doesn't need to be made more complicated than it already is.

* PR review, delete dangling with-parent-controls flag.
