3c884232fd gl_engine: rewrite the blending shader
Completely rewrite the GL backend shader to support advance blending and
correct the blending behavior.
Now the GL backend has the same blending result as SKIA and CanvasRenderingContext2D in browers did.

The formula is referenced from:

76f98008e8 gl_engine: optimize off-screen rendering
Performing a full-screen RenderPass resolve is too expensive.
Because most composite cases only require a small area to be rendered off-screen.
To improve performance, use the bounds of the Geometry for off-screen rendering whenever possible

f8626d13d1 gl_engine: fix clip path and bounds not correct
* Optimize clip logical, change to use GL_GRATER and keep incrace depth
  value, so no need to do depth clear after every clip draw.
* Correct geometry bounding box calculation, and make sure the bounds is
  larger than all vertices
* Limit drawing area for off-screen RenderPass with correct scissor box

68f7e4c245 gl_engine: enable msaa resolve in GLRenderPass
* use GLRenderBuffer in color and stencil attachment, also use x4 sample
  count by default.
* add msaa resolve logical at the end of a ComposeTask, so the normal
  color texture can get the final rendering result.

c8e0c48636 gl_engine: append stencil attachment in GLRenderTarget
Plans to use stencil to test support for path clipping and complex path rendering
When the tessellation algorithm cannot handle it.
