d6fffd13c2 api: revise the engine initializer for the 1.0 release.
This change introduces the CanvasEngine::All type to automatically
initialize the engines available on the current system.

These revisions improve the usability of these APIs.

Addtions:
- enum class CanvasEngine::All

Modifications:
- Result Initializer::init(CanvasEngine engine, uint32_t threads) ->
Result Initializer::init(uint32_t threads, CanvasEngine engine = tvg::CanvasEngine::All)

25a1321243 common: stroke dash offset support with new apis.
This change just allows users to use the offset of the stroke dash.
Actually feature enhacement has been introduced by
478e45f9f3.

@APIs:
uint32_t Shape::strokeDash(const float** dashPattern) ->
uint32_t Shape::strokeDash(const float** dashPattern, float* offset = nullptr)

Result Shape::strokeDash(const float* dashPattern, uint32_t cnt) ->
Result Shape::strokeDash(const float* dashPattern, uint32_t cnt, float offset = 0.0f)

Tvg_Result tvg_shape_set_stroke_dash(Tvg_Paint* paint, const float* dashPattern, uint32_t cnt) ->
Tvg_Result tvg_shape_set_stroke_dash(Tvg_Paint* paint, const float* dashPattern, uint32_t cnt, float offset)

Tvg_Result tvg_shape_get_stroke_dash(const Tvg_Paint* paint, const float** dashPattern, uint32_t* cnt) ->
Tvg_Result tvg_shape_get_stroke_dash(const Tvg_Paint* paint, const float** dashPattern, uint32_t* cnt, float* offset)

d81f5d29fb sw_engine/math: fine-tuning optimization
Try to minimize the use of sqrt() and arctan() calls
when possible. These calls can be relatively expensive
when accumulated within a single frame.

Also repalce the division with shift operation.
since split cubic function is one of the significant hot-spots
in the data processing, we could earn a noticable enhancement.

wg_engine: introduce a webgpu canvas(engine)
WebGPU is a Render Hardware Interface built on top of the various APIs 
provided by the driver/OS depending on your platform. 

WebGPU exposes an API for performing operations, 
such as rendering and computation, on a Graphics Processing Unit.

WebGPU official documentation: https://www.w3.org/TR/webgpu/

The new engine type introduced: tvg::CanvasEngine::Wg

The new canvas type introduced: tvg::WgCanvas

Example:
$meson setup build -Dengines=wg_beta

`
    // 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);

    // ...

    // terminate engine and window
    tvg::Initializer::term(tvg::CanvasEngine::Wg);
`

0cc6cfffef sw_engine/stroke: enhanced the quality of the dash line corners.
Previously, the engine didn't properly cover the dash line corner styles
because it considered a new line to start at the corner.

This update modifies the logic to recognize curved lines
as a single line, including the corners.

There may still be some quality issues,
but it's an improvement over the previous version.
