Remove FL_AUTO_DELETE_EVENT feature

It's not ripe for release yet and possibly not even needed
according to pyFLTK maintainers.

-  \note FLTK's auto-delete feature efficiently manages widget hierarchies in
-  C++ applications by automatically cleaning up. However, this feature can
-  cause issues when FLTK is used with reference-counting languages like Python,
-  where automatic deletion might interfere with reference counting. To address
-  this, auto-delete can be disabled for individual widgets. When
-  \ref Fl_Group::clear() is called, it sends an \ref FL_AUTO_DELETE event to
-  each widget. If a widget returns 1 in response to this event, it will not
-  be deleted. In a Python wrapper, this behavior would typically involve
-  decrementing the widget's reference count instead of deleting it.
