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
Automatic upgrade of OCCT code by command "occt_upgrade . -nocdl":
- WOK-generated header files from inc and sources from drv are moved to src
- CDL files removed
- All packages are converted to nocdlpack
Automatic update by command "occt_upgrade . -downcast"
C-style cast of Handle to that of derived type (now illegal) is replaced by call to DownCast()
Const reference local variables of Handle type initialized by result of DownCast are replaced by normal variables.
1. B-spline cache was moved into separated classes: BSplCLib_Cache for 2D and 3D curves and BSplSLib_Cache for surfaces.
2. The cache is used now in corresponding adaptor classes (Geom2dAdaptor_Curve, GeomAdaptor_Curve and GeomAdaptor_Surface) when the curve or surface is a B-spline.
3. Algorithms were changed to use adaptors for B-spline calculations instead of curves or surfaces.
4. Precised calculation of derivatives of surface of revolution is implemented for the points of surface placed on the axis of revolution (Geom_SurfaceOfRevolution.cxx)
5. Small modifications are made to adjust algorithms to new behavior of B-spline calculation.
6. Test cases were modified according to the modern behavior.
7. Changes in BOPAlgo_WireSplitter, BOPTools_AlgoTools, BRepLib_CheckCurveOnSurface and ShapeAnalysis_Wire to use adaptors instead of geometric entities
8. Allow Geom2dAdaptor and GeomAdaptor in case of offset curve to use corresponding adaptor for basis curve
Modification of test-cases according to the new behavior.
The constructors of classes from following files have been fixed to ensure that all non-static fields are initialized:

Sometimes curve or surface, which is defined as C0, has continuity G1 or above. Offset can be built from these shapes.
Therefore, this extended checking was added into SetBasisCurve and SetBasisSurface methods.
Main changes in function BRepOffset_Tool::ExtentFace(...):
* "return" is added if intersection (in 2D-space) between two edges in a face cannot be found.
Basis curve/surface continuity value found (if G1-checking is OK) is set up as BasisContinuity (see myBasisCurveContinuity and myBasisSurfContinuity members which is returned by GetBasisCurveContinuity and GetBasisSurfContinuity() methods). This fact is used in Geom2dAdaptor and in GeomAdaptor classes.
Possibility is entered, which allows for basis elements of offset curve/surface to avoid of C0-checking.
Test cases were changed according to their new behavior.
Test-cases for issue #25124
For fix this case in method Geom2dInt_Geom2dCurveTool::NBSamples() number of samples for 2d offset and trimmed curve is computed as max value from number of samples for other curve and number of samples for basis curve.
Test case for issue CR24800
