Constify scope reference in NetEConstParam and NetECRealParam 

Parameter expressions need to remember the scope they have been declared in
so that the code generator backends can insert the right parameter
reference, rather than a constant value.

Currently the scope is stored as a non-const reference. But that is not
needed. Mark the scope reference as const so NetEConstParam and
NetECRealParam can be created when only a const scope reference is
available.
