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:

since the framebuffer will draw back to parent RenderPass, it can be
reused in next compose rendering.
So instead of create framebuffer every time when beginCompose is called, we
trying to reuse the framebuffer created before in the same stack level
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);

* Use uniform block to pack all color informations
* Move the actual gl draw call into GlRenderer::sync function, so all
data is been uploaded into GPU
* Make GlRenderTask simple and generic for direct gl draw
