libstdc++: Move _Index_tuple, _Build_index_tuple to <type_traits>.
As preparation for implementing std::constant_wrapper that's part of the
C++26 version of the <type_traits> header, the two classes _Index_tuple
and _Build_index_tuple are moved to <type_traits>. These two helpers are
needed by std::constant_wrapper to initialize the elements of one C
array with another.
Since, <bits/utility.h> already includes <type_traits> this solution
avoids creating a very small header file for just these two internal
classes. This approach doesn't move std::index_sequence and related code
to <type_traits> and therefore doesn't change which headers provide
user-facing features.
libstdc++-v3/ChangeLog:
* include/bits/utility.h (_Index_tuple): Move to <type_traits>.
(_Build_index_tuple): Ditto.
* include/std/type_traits (_Index_tuple): Ditto.
(_Build_index_tuple): Ditto.
