Vulkan: Improve Bresenham line emulation.
Clamps the vertex position to the subpixel grid before interpolation.
This will give more correct results on systems that have less than
8 bits of subpixel accuracy.
Also uses a more accurate formulation for the emulation filter in the
fragment shader using dfdx and dfdy.
Fixes line raster CTS tests on SwiftShader. Still does not produce spec
conformant lines. Updates the public docs to indicate this.

Move Vulkan GlslangWrapper code to a shared location.
Metal backend will reuse Vulkan's GlslangWrapper code.
The Metal backend will use this code to translate glsl to spirv then
cross compile to Metal Shading Language using spirv-cross.
So the source code of GlslangWrapper should be moved outside vulkan folder.

Vulkan: Add design docs on line segment raster.
The docs are based on an internal google document available at
go/vangle-line-rasterization. The link won't work for non-Googlers.
Also cleans up the format of the markdown file somewhat.

Vulkan: Write design doc explaining SPIR-V generation.
The two-pass approach first uses ANGLE's shader translator followed by
glslang. The doc explains it in more detail with links.
