Add configurable short wall/perimeter cleaning for Arachne (#2790)

Browse Source 
* add feature to add configurable value to clean/remove short un-closed walls/perimeters, to improve print times and reduce stringing (and generally lead to a cleaner print).

* fixes to short wall removal, which no longer affects bottom or top surfaces. allowed adjusting Top-surface threshold (renamed from One wall threshold for clarity) when short wall removal value is configured above default of 0.5.

* small fix for toggle_line for min_width_top_surface, to only be visible if min_length_factor > 0.5 and arachne is enabled.

* Use copy of input_params

* revert `One wall threshold"` string change
