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.

f611b48c71 graphicsdriver/opengl: Use native GLES functions for mobiles
After this change, GL functions for mobiles, especially Android, are
native ones instead of golang.org/x/mobile/gl functions in order to
reduce goroutine context switches.

On gomobile-build, golang.org/x/mobile/gl functions are still used.
