407fc84796 common: spec out Scene Clipper 
Scene Clipper is an unusual feature
that is too unstable and ambiguous in ThorVG.

Users can achieve the same functionality
with multiple composed shapes instead of scene clipping.

468b132739 renderer: enhanced shared surface handling with mutex implementation 
Introduced a dedicated mutex for each surface instance
to ensure safe sharing between the loader, renderer, and engine.

This enhancement allows for secure modification and access to bitmap data,
addressing potential concurrency issues.

Multiple Picture instances can now safely share a single loader instance,
optimizing performance.

This change builds upon the previous Loader Cache improvements:

1a6571f596 wg_engine: refactor render targets handling 
For further development of features, we need to create off-screen buffers that will allow us to implement functionality related to composition and blending, as well as for loading data to system memory from the framebuffer. Separating the framebuffer into a separate entity allows you to create several instances of them, switch between them, and blend them according to given rules.

For current time we have only a single render target instance, that have a handle to drawing into surface surface, like a native window.

New approach allows:
- offscreen rendering
- render pass handling
- switching between render targets
- ability to render images, strokes and shapes into independent render targets

548962f5f8 apis/engines: Revise the clear() buffer behavior. 
ThorVG has offered an option to clear the buffer since version 1.0.
This is essential when users utilize the canvas target buffer
with the main render target. They share the buffer
and need to draw contents onto the existing contents.

API:
Result Canvas::clear(bool free = true)
-> Result Canvas::clear(bool paints = true, bool buffer = true)

Tvg_Result tvg_canvas_clear(Tvg_Canvas* canvas, bool free);
-> Tvg_Result tvg_canvas_clear(Tvg_Canvas* canvas, bool paints, bool buffer);

wg_engine: introduce a webgpu canvas(engine) 
WebGPU is a Render Hardware Interface built on top of the various APIs 
provided by the driver/OS depending on your platform. 

WebGPU exposes an API for performing operations, 
such as rendering and computation, on a Graphics Processing Unit.

WebGPU official documentation: https://www.w3.org/TR/webgpu/

The new engine type introduced: tvg::CanvasEngine::Wg

The new canvas type introduced: tvg::WgCanvas

Example:
$meson setup build -Dengines=wg_beta

`
    // init engine webgpu
    tvg::Initializer::init(tvg::CanvasEngine::Wg, 0);

    // create wg canvas
    auto canvasWg = tvg::WgCanvas::gen();
    canvas_wg->target(glfwGetWin32Window(window), width, height);

    // ...

    // terminate engine and window
    tvg::Initializer::term(tvg::CanvasEngine::Wg);
`
Still this feature is under the beta
