Modeling Data - Refactor offset curve and surface evaluators (#930)

Browse Source 
Extract derivative calculation logic from GeomEvaluator and
  Geom2dEvaluator classes into dedicated utility headers:
- Geom_OffsetSurfaceUtils.pxx for 3D offset surface derivatives
- Geom_OffsetCurveUtils.pxx for 3D offset curve derivatives  
- Geom2d_OffsetCurveUtils.pxx for 2D offset curve derivatives
- Geom_ExtrusionUtils.pxx for extrusion surface calculations
- Geom_RevolutionUtils.pxx for revolution surface calculations

Utility functions provide unified handling of singular and non-singular
  cases with osculating surface support for higher-order derivatives.

Buffer management uses NCollection_LocalArray for stack-safe allocation
  with heap fallback when sizes exceed expected limits.

Test case expectations updated to reflect improved calculation accuracy.
