testsuite: std_list handling for { target c++26 }

As with c++23, we want to run { target c++26 } tests even though it isn't
part of the default std_list.

C++17 with Concepts TS is no longer an interesting target configuration.

And bump the impcx target to use C++26 mode instead of 23.

gcc/testsuite/ChangeLog:

* lib/g++-dg.exp (g++-dg-runtest): Update for C++26.
