PR libstdc++/82254 fix std::is_nothrow_invocable_r w.r.t throwing conversions
PR libstdc++/82254
* include/std/type_traits (__is_invocable): Add partial specialization
for INVOKE<void> case and remove is_void<R> check from partial
specialization for INVOKE<R> case.
(__is_nt_invocable_impl): New helper for is_nothrow_invocable_r.
(is_nothrow_invocable_r): Use __is_nt_invocable_impl.
* testsuite/20_util/is_nothrow_invocable/value.cc: Add tests for
conversions that can throw or fail to convert. Use static assert
strings to explain negative results.
* testsuite/20_util/is_nothrow_invocable/value_ext.cc: Use
is_nothrow_constructible in is_nt_invocable_conv.
