bugfix [#28111] material.pop breaks mt->mat_nr
create a new parameter for materials.pop() to not remove material slot.
this way the mat_nr is still the old one.
for the default behaviour we now have material remapping (i.e. data_delete_material_index_id(id, index)).
This new function is brought from the material_slot remove function.
