libstdc++: add a constexpr macro for C++26
Following the precedent of _GLIBCXX20_CONSTEXPR.
It will be used to decorate some functions which have been made
constexpr in C++26 (for instance P2562R1, and maybe P3508R0, P3369R0,
...).
libstdc++-v3/ChangeLog:
* include/bits/c++config (_GLIBCXX26_CONSTEXPR): New macro.
