Symmetric gradient operator for TGV regularization (in-place, f32)

Computes the symmetric gradient tensor from a vector field w = (wx, wy, wz). The output is a 6-component symmetric tensor: q[0] = ∂wx/∂x (Sxx) q[1] = (∂wx/∂y + ∂wy/∂x) / 2 (Sxy) q[2] = (∂wx/∂z + ∂wz/∂x) / 2 (Sxz) q[3] = ∂wy/∂y (Syy) q[4] = (∂wy/∂z + ∂wz/∂y) / 2 (Syz) q[5] = ∂wz/∂z (Szz)
