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.

graphicsdriver/opengl: Use glBindAttribLocation instead of glGetAttribLocation
...
Attribute variables are often optimized out and it is really hard
to prevent this.
Instead of implicit indices of attribute variables, use explicit
indices by glBindAttribLocation.
