Intercurve fillet uses endpoint constraints for improved accuracy, but before this
commit was only considering a coincident constraint. Now it also considers an endpoint
tangency or perpendicular.
delConstraintOnPoint with coincidentonly=false, was not checking endpoint perpendiculars and
would therefore fail to delete them.

=========================================
This commit introduces two functions to operate on all datum constraints exclusively:
- Make all datum constraints driving or not driving, depending on the argument.
- Move all datum constraints at the end of the constraint list.
The practical use an ongoing effort towards improving the block constraint behaviour, that will be defered to 0.19

OCCT Geom2dAPI_InterCurveCurve based intersector does not detect intersection with the endpoint of a tangent line:
https://tracker.dev.opencascade.org/view.php?id=30217
This is a work-around that introduces endpoints of secondary curves as intersections, and uses projection to reject
projections further away than precision::confusion().

=========================================================
This ensures that the exception back in the c++ that invoked python retains the type of exception and can be properly catched.
====================================================
Part of the geometry was using CADKernelError and part was using RunTimeError exceptions, so unify criteria.
Runtime is very generic and does not need to stem from OCCT.
- Also rename of a typo basic to basis, to be coherent with OCCT terminology
