libstdc++: Reorder constructors in <sstream>
This groups all the constructors together, consistent with the synopses
in the C++20 standard.
libstdc++-v3/ChangeLog:
* include/std/sstream (basic_stringbug, basic_istringstream)
(basic_ostringstream, basic_stringstream): Reorder C++20
constructors to be declared next to other constructors.
