GLSL: workaround texture sampling with offset on depth arrays.

When calling textureSample() or textureSampleCompare() on a texture_depth_2d_array with an offset, use GLSL's
textureGradOffset() instead of textureOffset(), and explicitly
pass dFdx and dFdy of the texture coords parameter as the gradients.
