wg_engine: Added shape opacity value usage

Browse source 
[issues 1479: Opacity](#1479)

Usage example:

    // prepare a shape (Rectangle + Rectangle + Circle + Circle) with opacity
    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
    shape1->opacity(128)                               //opacity
    canvas->push(std::move(shape1));
