0024773: Convertation of the generic classes to the non-generic. Part 7

1) Generic classes:

 "GccGeo_Circ2dTanOn",
 "GccGeo_Circ2d2TanRad",
 "GccGeo_Circ2d2TanCen",
 "GccGeo_Circ2d2TanOnRad",
 "GccGeo_CurvePGTool"

from "GccGeo" package converted to the non-generic classes and moved to the "Geom2dGcc" package. Names of this classes were changed to:

 "Geom2dGcc_Circ2dTanOnGeo",
 "Geom2dGcc_Circ2d2TanRadGeo",
 "Geom2dGcc_Circ2d2TanCenGeo",
 "Geom2dGcc_Circ2d2TanOnRadGeo",
 "Geom2dGcc_CurveToolGeo".

Also "GccGeo_PanGenCurve" unused generic class was deleted. And "GccGeo" package was deleted.
