0025923: Remove small wires on face read from STEP

Browse Source 
The analysis of small area in the method ShapeAnalysis_Wire::CheckSmallArea is performed the following way:
- On the fisrt step algorithm produces a rough estimation of part of surface area.
- In a case if obtained estimation is less than tolerance then evaluate real area and comapre this value with tolerance.
- New flag has been added to XSTEPResource/IGES. In a case if flag is true the faces with small 3d area is removed from ShapeFix context.

Test-case for issue #25923 and update test-cases in de group according to the new behavior.
