The geo nodes implementations of the `mix`, `addition`, `multiplication` and `subtraction` color mix modes are both faster and have better numerical properties than the ones we use in Cycles, OSL and EEVEE. This PR ports the geo nodes implementations of those color mix modes to Cycles, OSL and EEVEE. Additionally, the SVM mix function implementation is templatized and a new function called "endvalue_preserving_mix" is added for the alternative variant of linear interpolation.
