Neon kernel used to add the offset contribution after NEGEMMLowpMatrixMultiplyKernel.
The computation is performed in-place
This kernel takes a final int32 accumulator value (the output of NEGEMMLowpMatrixMultiplyKernel), and adds to it the offset contribution of matrix A and matrix B in-place.
The final result is:
mm_result[i][k] = mm_result[i][k] + (vector_sum_col[k] * a_offset) + (vector_sum_row[i] * b_offset) + (a_offset * b_offset * k)
