4th-axis fixes and improvements

Fix rotational orientation of pockets.  Need to apply same fix to ProfileFaces.
Fix final depth issue based upon error in rotational orientation fixed here.
Add property, `LimitDepthToFace` to facilitate easier pockets and face profiling on rotational-enabled operations.
Hide rotational support properties when operations do not use rotation.
Remove unnecessary property, `B_AxisErrorOverride`, and delete dead code that used it.
