[analyzer] [NFC] Remove unused argument from makeSymExprValNN

[NoQ]

The contract of this method is pretty unclear. I guess we may eventually have to bring the State back at some point, but i wouldn't mind having it shorter now.

   /// Simplify symbolic expressions within a given SVal. Return an SVal
   /// that represents the same value, but is hopefully easier to work with
   /// than the original SVal.
   virtual SVal simplifySVal(ProgramStateRef State, SVal Val) = 0;
 
   /// Constructs a symbolic expression for two non-location values.
