feat(webgl): Migrate to pure WebGL 2.0 and fix GL canvas layering

Browse source

Update submodules and build config for pure WebGL 2.0 (drop -sFULL_ES3):
- kicad: VBO-based drawing, compositor FBO rewrite, shader conversion
- wxwidgets: Fix z-index layering so GL canvas renders above 2D UI canvas
- Build: Remove FULL_ES3 from linker flags
- GAL tests: White background, opaque alpha, shared shader converter,
  updated baseline screenshots
