Change the semantic of the last template parameter of Assignment from "Scalar" to "SFINAE" only.

Browse Source 
The previous "Scalar" semantic was obsolete since we allow for different scalar types in the source and destination expressions.
On can still specialize on scalar types through SFINAE and/or assignment functor.
