c++: Link extended FP conversion pedwarns to -Wnarrowing [PR111842]
Several users have been confused by the status of these warnings,
which can be misunderstood as "this might not be what you want",
rather than diagnostics required by the C++ standard. Add the text "ISO
C++ does not allow" to make this clear.
Also link them to -Wnarrowing so that they can be disabled or promoted
to errors independently of other pedwarns.

gcc/cp/ChangeLog:
* call.cc (convert_like_internal): Use OPT_Wnarrowing for
pedwarns about illformed conversions involving extended
floating-point types. Clarify that ISO C++ requires these
diagnostics.
gcc/testsuite/ChangeLog:
* g++.dg/cpp23/ext-floating16.C: New test.
* g++.dg/cpp23/ext-floating17.C: New test.
