[PATCH v5 7/7] libstdc++: Set __cpp_lib_submdspan to 202411.

[Luc Grosheintz]

The submdspan feature is complete and this commit sets the feature
testing macros accordingly. Also makes the feature testing macro
submdspan depend on constant_wrapper.

Also changes the value of the internal feature testing macro for padded
layouts to 202403.

libstdc++-v3/ChangeLog:

        * include/bits/version.def (submdspan): Set to 202411 add
        dependency.
        * include/bits/version.h: Regenerate.
