Roll WebGL 3f6583d..6f0b34a

Tests removed from suppresion:
conformance/extensions/oes-texture-float.html
conformance2/rendering/vertex-id.html

Newly suppressed on D3D9:
conformance/extensions/webgl-depth-texture.html

Also some tests are updated to get rid of empty fragment-shader
(or called gl.drawBuffers([gl.NONE]).
We should be finally able to land patches fixing drawbuffers without fs output issue.
