0023620: Follow up of 0022939 - make Bezier curve/surface evaluation thread-safe

Browse Source 
1. Remove cache from Geom_BezierCurve, Geom2d_BezierCurve and Geom_BezierSurface
2. Add cache for Bezier curves into GeomAdaptor_Curve, Geom2dAdaptor_Curve and GeomAdaptor_Surface
3. Update comments in corresponding cache classes
4. Avoid frequent down-casting to B-splines in adaptors
