Sergii Liebodkin 938b69688d wg_engine: Added ability to draw multiple solid color filled shapes

[issues 1479: Shape](https://github.com/thorvg/thorvg/issues/1479)

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);

    // prepare a shape (Rectangle + Rectangle + Circle + Circle)
    auto shape1 = tvg::Shape::gen();
    shape1->appendRect(0, 0, 200, 200);                //x, y, w, h
    shape1->appendRect(100, 100, 300, 300, 100, 100);  //x, y, w, h, rx, ry
    shape1->appendCircle(400, 400, 100, 100);          //cx, cy, radiusW, radiusH
    shape1->appendCircle(400, 500, 170, 100);          //cx, cy, radiusW, radiusH
    shape1->fill(255, 255, 0);                         //r, g, b

    canvas_wg->push(std::move(shape1));

    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();
