With WebGL1, an extension is required for dFdx. On the other hand, with WebGL2, GLSL ES 300 is required and the extension is forbidden. This change fixes shaderir/glsl to switch the output depends on the WebGL version. This change also adds a new build tag 'ebitenwebgl1' forcing WebGL 1. Updates #1404
