0815366763 wg_engine: clippath optimization 
Full review of clipping workflow.

Before we are used separate render target for each clip path and compute shader to find clip path intersections with AND logic.
Now we are using depth buffer and transactions from depth to stencil and back to get AND logic intersections,
Compute shaders, layouts and pipelines was removed

732a2be7e8 wg_engine: scene blending optimization 
- used hardware blending stage for scene blending
- used AABB for scene blending
- reduced number of offfscreen buffers coping
- reduced number of render pass switching
- used render pipelines abilities to convert offscreen pixel format to screen pixel format
- removed unused shaders

88b4f75e4f webgpu: shaders refactoring 
Deep shader refactoring for the following purposes:
* used pre-calculated gradient texture instead of per-pixel gradient map computation
* used HW wrap samples for fill spread setting
* unified gradient shader types
* used single shader module for composition instead of signle module per composition type
* used single shader module for blending for each of fill type (solid, gradient, image) instaed of signle module per blend type
* much easier add new composition and blend equations
* get rided std::string uasge
* shaders code is more readable

2c948a33d3 wg_engine: ClipPath support 
[issues 1479: ClipPath](#1479)

Supports ClipPath composition.
Clip path composition is an only composition type who doesn't ignore blend method.
Clip path is a combination of composition approach and blend approach using compute shader
