853c1f2b92 internal/shaderir/glsl: Bug fix: Remove uncalled functions 
Some built-in functions like dFdx is not available in a vertex shader,
then a function that calls such built-in function should not be in
a vertex shader.

Closes #1701

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.
