glsl/cs: Initialize gl_LocalInvocationIndex in main()

We initialize gl_LocalInvocationIndex based on the extension spec
formula:

    gl_LocalInvocationIndex =
        gl_LocalInvocationID.z * gl_WorkGroupSize.x * gl_WorkGroupSize.y +
        gl_LocalInvocationID.y * gl_WorkGroupSize.x +
        gl_LocalInvocationID.x;
