common sw_engine: Implement ClipPath feature
Paint object can composite by using composite API.
ClipPath composite is clipping by path unit of paint.
The following cases are supported.
Shape->composite(Shape);
Scene->composite(Shape);
Picture->composite(Shape);
Add enum
enum CompMethod { None = 0, ClipPath };
Add APIs
Result composite(std::unique_ptr<Paint> comp, CompMethod method) const noexcept;
* Example: Added testClipPath
Changes:
1. New shape->duplicate(Shape) api.
2. New example: testDuplicate
3. Added capi binding for duploicate api
4. Added capi duplication test in testCapi.c
Description:
Added implementation of duplicate api. For now it supports stroke
properties and shape properties (fill color, path) duplication.
TODO:
Implement gradient properties duplication
remove unnecessary condition.
implementation won't be included multiple times not like headers.
Thus this condition is unnecessary.

Introduce internal PaintMethod since there more derived paint classes are coming.
This PaintMethod is a sort of Strategy Pattern method.

transform interfaces are getting duplicated in derived classes.
we moved to the super for smaller apis count.
Applied strategy pattern to hide the inheritance.
