remove unused header

it will never be used either as opm requires c++17 now
which means final is always supported

- * \file
- * \brief This file provides a wrapper around the "final" C++-2011 statement.
- *
- * The "final" C++-2011 statement specifies that a virtual method cannot be overloaded by
- * derived classes anymore. This allows the compiler to de-virtualize calls to such
- * methods and is this an optimization. (it also prevents the programmer from creating a
- * new method instead of overloading an existing one, i.e., it is nice to have from a
- * code quality perspective.) Since not all compilers which must be supported by OPM
- * feature the "final" qualifier, this method provides a wrapper macro around it.
