0027325: [Regression to 6.9.1] geom/revolution_00/A1: BOPTools_AlgoTools2D::AttachExistingPCurve doesn't work

1. Check, if edge is same-range, is now made with some tolerance (not strictly) in GeomLib_CheckCurveOnSurface class. Default value of this tolerance is Precision::PConfusion(). However, this value can be changed with corresponding interface.

2. DRAW-command "attachpcurve" has been added to BOPTest_UtilityCommands.cxx file. This command creates p-curve of given edge on given face. It can assign 2D-curve of one of the edge already included in the face or (if it is not possible) rebuilds new 2D-curve.

Creation of test case for this issue.
Adjusting test case boolean volumemaker A8 according to its new behavior on Windows.
