feat(webgl): Add WEBGL_GAL implementation (compiles, not yet rendering)

Browse source

Copy and adapt OpenGL GAL to WebGL:
- Copy all OpenGL GAL source files to tests/gal-regression/wasm/webgl/
- Rename classes from OPENGL_* to WEBGL_*
- Add kiglew.h with WebGL2/GLES3 headers and GLEW stubs
- Add webgl_antialiasing.h/cpp adapted for WEBGL_COMPOSITOR
- Add shader generator (generate_shaders.py) for WASM build
- Update Makefile with all KiCad dependencies (C++20, GLM, clipper2, etc.)

Build produces 544KB JS + 4.9MB WASM. Tests run but render blank
(expected - GL context initialization needs WebGL adaptation).
