Define boost::wrapexcept when BOOST_NO_EXCEPTIONS is defined, to enable boost::make_exception_ptr

Since Boost.Exception started using boost::wrapexcept in implementation
of boost::exception_ptr, we need to define it even when
BOOST_EXCEPTION_DISABLE is defined, otherwise it won't compile:

$ clang++ -DBOOST_EXCEPTION_DISABLE -w -x c++ \
  /usr/include/boost/exception_ptr.hpp -fsyntax-only
In file included from /usr/include/boost/exception_ptr.hpp:9:
/usr/include/boost/exception/detail/exception_ptr.hpp:87:49: error: use of
undeclared identifier 'wrapexcept'
        return exception_ptr(boost::make_shared<wrapexcept<E> >(cp));
                                                ^

-## Changes in Boost 1.73.0
+## Changes in 1.73.0
 
 * Added an overload of `throw_exception` that takes a `boost::source_location`
   object.
-  
+
 NOTE: Projects using `BOOST_THROW_EXCEPTION` with exceptions disabled will need
       to add a definition of this new overload.
