Test synched with khronos.

The code path where packed_depth_stencil extension doesn't exist has also been
tested by faking m_isDepthStencilSupported = false in WebGLRenderingContext.

This is half of the effort to fix the issue.  We also need to map the enum in
command buffer so INVALID_ENUM won't be generated.
