The Trivial Relocation feature has been removed from the C++26 working draft. Based on discussions in Kona, it is unlikely that the "replaceable" type concept will come back in the C++29 time frame. Since we don't have a use for the type trait in the library at the moment, remove the code associated to it. If we end up needing something like it in the future, we can always add it back.
