Mismatch between HM and CD in ALF filter output calculation

Description

There is a mismatch between HM and CD in ALF filter output calculation as a result of integration of H0068. The existing HM code will transmit ALF coefficients in the order: C0, C1, C4, C3, C2, C5, C6, C7, C8, C9 instead of the "natural" order of: C0, C1, C2, C3, C4, C5, C6, C7, C8, C9. The fixed code does not result in any BD-Rate difference since only the order of transmission of coeffs is different, but it will result in a different bitstream.
