wg_engine: winding fill rule
...
[issues 1479: FillRule](#1479 )
Introduced fill rule winding
This rule makes sense only if path have some self intersections.
In all other cases shapes are filled by even-odd behavor.

wg_engine: shape bbox based rendering (optimization)
...
Before the current changes, all surfaces were painted using a full-screen overlay, no matter how large the object was rendered. This approach is redundant and required reorganization. At the moment, all objects are rendered using an overlay equal to the box of the object itself, which reduces the cost of filling the surface.
Also surfaces and images were divided into different entities, which reduces the pressure on memory.
Also geometry data for rendering and geometry data for calculations in system memory were logically separated.

In order to build you need third party libraries. Before you start please read this: [LearnWebGPU](https://eliemichel.github.io/LearnWebGPU/getting-started/hello-webgpu.html )
Usage example:
// init glfw
glfwInit();
// create a windowed mode window and its opengl context
glfwWindowHint(GLFW_CLIENT_API, GLFW_NO_API);
GLFWwindow* window = glfwCreateWindow(800, 800, "WebGPU base app", nullptr, nullptr);
// get window size
int width{}, height{};
glfwGetWindowSize(window, &width, &height);
// 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);
//Test for Stroke Dash for Arc, Circle, Rect
auto shape = tvg::Shape::gen();
shape->appendArc(70, 600, 160, 10, 30, true);
shape->appendCircle(70, 700, 20, 60);
shape->appendRect(130, 710, 100, 40);
shape->strokeFill(255, 0, 0);
shape->strokeWidth(5);
shape->strokeJoin(tvg::StrokeJoin::Round);
shape->strokeCap(tvg::StrokeCap::Round);
float dashPattern[2] = {20, 10};
shape->strokeDash(dashPattern, 2);
if (canvas_wg->push(std::move(shape)) != tvg::Result::Success) return;
while (!glfwWindowShouldClose(window)) {
// webgpu
canvas_wg->draw();
canvas_wg->sync();
// pull events
glfwPollEvents();
}
// terminate engine and window
tvg::Initializer::term(tvg::CanvasEngine::Wg);
glfwDestroyWindow(window);
glfwTerminate();
