libstdc++: Fix build for targets without _Float128 [PR109921]

My r14-1431-g7037e7b6e4ac41 change caused the _Float128 overload to be
compiled unconditionally, by moving the USE_STRTOF128_FOR_FROM_CHARS
check into the function body. That function should still only be
compiled if the target actually supports _Float128.

libstdc++-v3/ChangeLog:

PR libstdc++/109921
* src/c++17/floating_from_chars.cc: Check __FLT128_MANT_DIG__ is
defined before trying to use _Float128.
