* Merge bitcoin/bitcoin#23181: refactor: remove references to deprecated values under std::allocator

ea4b61a1570178ebe5851b5fb4065222e3926f7e refactor: remove references to deprecated values under std::allocator (Pasta)

Pull request description:

  Removes usages of allocator::pointer, allocator::const_pointer, allocator::reference and allocator::const_reference which are deprecated in c++17 and **removed** in c++20. See https://en.cppreference.com/w/cpp/memory/allocator

  Also prefers `using` over `typedef` see: https://isocpp.github.io/CppCoreGuidelines/CppCoreGuidelines#Rt-using I'll be happy to revert this if requested so
