Fix axis constraints API and documentation:v5.12.1

This should have been done properly for 5.12.
Since this API was introduced in 5.12.0, we simply hide the
documentation for the old properties and make sure the properties we want
to expose are documented:

* Document the xAxis and yAxis properties.
* Deprecate the {min,max}imum{X,Y} properties, and hide them in the
  documentation.

Fixes: QTBUG-73137
