be538bacf7 gl_engine: Fix calculation error in path triming 
Basically rewrite the PathTrim code, correct the Line and Bezier split
function calling.
Also the trim situation where start is greater than end can be handled correctly.

36e5f68222 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.

c5a7d76109 sw_engine: replaced longjmp with returns 
Since longjmp is not yet fully supported on Wasm (emscripten uses
JS to make the jumps and requires slow jumps), but also because
longjmp is hard to reason about, this patch replaces it with
return values. The logic stays exactly the same.

52cf31a79d renderer: make the file io configurable 
certain systems, may not support file I/O operations.
ThorVG should provide users with an option to configure
builds according to their requirements.

This ensures that file I/O calls are avoided,
preventing potential crashes.

Please use the meson '-Dfile=true/false' option for this.

Please note that "THORVG_FILE_IO_SUPPORT" might be expected
for your thorvg manual build.

8b37ec5d9c gl_engine: seperate the index buffer from vertex buffer 
WebGL has a strict rule that does not allow the same GLBuffer
to be bound to both ARRAY_BUFFER and ELEMENT_ARRAY_BUFFER at the same time.
(https://registry.khronos.org/webgl/specs/latest/1.0/#5.14.5)

To support WebGL in the future, a separate GLBuffer is used to store index data.
