capi examples: Added scene API C bindings. 
Scene CAPI allows to use scene functionaliy in C applications such as
set opacity to few shapes at one time or implement transparent layers.

@API Additions:
```c
Tvg_Paint* tvg_scene_new();
Tvg_Result tvg_scene_reserve(Tvg_Paint* scene, uint32_t size);
Tvg_Result tvg_scene_push(Tvg_Paint* scene, Tvg_Paint *paint);
```

Examples:
```c
Tvg_Paint *scene = tvg_scene_new();

Tvg_Paint *shape1 = tvg_shape_new();
tvg_shape_append_rect(shape1, 10, 10, 100, 100, 0, 0);
tvg_shape_set_fill_color(shape1, 255, 0, 0, 255);

Tvg_Paint *shape2 = tvg_shape_new();
tvg_shape_append_rect(shape2, 120, 10, 100, 100, 0, 0);
tvg_shape_set_fill_color(shape2, 255, 0, 0, 255);

tvg_scene_push(scene, shape1);
tvg_scene_push(scene, shape2);

tvg_paint_set_opacity(scene, 100);

tvg_canvas_push(canvas, scene);
```

sw_engine shape: performance optimization. 
we introduced shared memory pool for avoiding reallocate memory
while it process the stroke outlines, It experimentally increase
the outline data if we use the allocated memory for multiples shape strokes,
we don't need to alloc/free memory during the process.

This shared outline memory is allocated for threads count
so that we don't interrupt memory access during the tasks.

0399d84478 common paint: introduce opacity() method. 
We introduced separate opacity interface to adjust alpha value by paint.
This opacity will affect to whole paint image if paint is a group of paints.

Also, this opacity is to multipy with fill/stroke alpha values.
This means if the opacity is valid, the paint might deal with a composition step,
which is very expensive due to additional rendering step.

One tip is, if you want to toggle on/off for a certian paint,
you can set opacity to 255 or 0.

@API Additions:

Result Paint::opacity(uint8_t o) noexcept;
uint8_t Paint::opacity() const noexcept;
