Improve Debug Panel UI (#1621)

* Inline parameters with their respective operator

* Restrict min number of polygons to 0

* Simplify high poly mesh operator execution

* Clear debug attributes when purging ifc

* Poll if ifc file exists in operators

* Poll if ifc filepath exists before import

* Delete leftover whitespaces
