Implement GLSL writer backend.
This is a modified version of the HLSL writer.
Basic types, arrays, entry points, reserved keywords, uniforms,
builtin uniforms, structs, some builtin functions, zero initialization
are implemented. Textures, SSBOs and storage textures in particular are
unimplemented. All the unit tests "pass", but the output is not correct
in many cases.
triangle.wgsl outputs correct vertex and fragment shaders that pass
GLSL validation via glslang. compute_boids.wgsl outputs a valid but not
correct compute shader.
