1806b32971 common: optimization pImpl data structures 
ThorVG pImpl idiom caused internal data to be scattered
across hierarchical classes. This refactoring consolidates
the data by inheriting pImpl internally, reducing memory
allocation counts and eliminating unnecessary strategy methods.

6761c5c2a0 API: Replace the Canvas::clear() API with Canvas::remove() & draw() 
Added a `clear` parameter to Canvas::draw(), allowing users to decide
whether to clear the target buffer before drawing.

To remove the paints from a canvas, please use Canvas::remove()

C++ API Removals:
- Result Canvas::clear(bool paints, bool buffer)

C++ API Modifications:
- Result Canvas::draw()
 -> Result Canvas::draw(bool clear)

C API Removals:
- Tvg_Result tvg_canvas_clear(bool paints, bool buffer)

C API Modifications:
- Tvg_Result tvg_canvas_draw(Tvg_Canvas* canvas)
 -> Tvg_Result tvg_canvas_draw(Tvg_Canvas* canvas, bool clear)

445000ba66 common: improve the rendering pipeline 
enhanced the rendering composition target to better support features such as
alpha blending, blending, masking, post effects, and more.
This allows rasterizers to prepare the composition context with more precise control.

Additionally, resolved a crash in the software engine's post-effect process
caused by a buffer size mismatch during XY buffer flipping.
