[PR libgfortran/78314] Fix ieee_support_halting
ieee_support_halting only checked the availability of status
flags, not trapping support. On some targets the later can
only be checked at runtime: feenableexcept reports if
enabling traps failed.
So check trapping support by enabling/disabling it.
Updated the test that enabled trapping to check if it is
supported.
