libstdc++: Fix long double to_chars testcase [PR98384]
The testcase was failing to compile on some targets due to its use of
the non-standard functions nextupl and nextdownl. This patch makes the
testcase instead use the C99 function nexttowardl in an equivalent way.
libstdc++-v3/ChangeLog:
PR libstdc++/98384
* testsuite/20_util/to_chars/long_double.cc: Use nexttowardl
instead of the non-standard nextupl and nextdownl.
