feat(auto_export): restructured & improved changed parameters detection

* now all centralized in the operator's did_export_settings_change() function
 * now works correctly ! ie only compares the parameters for auto & gltf
at the time of exporting ! ie it does not matter anymore how many parameters you changed, until you save/export
 * this solves a lot of randomness bugs in change detection
 * related & various cleanups
