Hajime Hoshi b1d7a5f595 shaderir/glsl: Enable dFdx for WebGL
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.
