refactor display and disp functions (bug #49794)
* pr-output.cc (Fdisp, Ffdisp): Tag with dispatch classes.
(Fdisplay): New function.
* ov-class.cc (octave_class::print_with_name):
Simply call octave_base_value::print_with_name.
* ov-classdef.cc (octave_classdef::print): Simply call print_raw.
(octave_classdef::print_with_name):
Simply call octave_base_value::print_with_name.
* variables.cc (bind_ans): Call display function to print result.
* pt-assign.cc (tree_simple_assignment::rvalue1,
tree_multi_assignment::rvalue): Likewise.
* pt-id.cc (tree_identifier::rvalue): Likewise.
* display.m: Delete.
* scripts/general/module.mk: Update.
