validation_error implicit copy/move constructor

We had a number of program options , most `uint*_t` and one additional that is a `vector` using `mutlitoken` ) that began erroring. This was working, but post updates to boost 1.88.0 (prior 1.75.0) + clang 19.1.7, it now produces an error. We have opted to throw some push/pops around this in our code right now to suppress the issue but would like to address it with a more appropriate fix. Included below is the warning for one of the numeric options. We did not investigate these as much as we did the arguments_map ( https://github.com/boostorg/program_options/issues/146 ), but would believe this one is better handled by adding default constructors (this might even be a case where `BOOST_DEFAULTED_FUNCTION` should be updated) as nothing jumps out as being a pointer where special handling may be required but would like those with more knowledge of the library to weigh in.

Bắt đầu trong errors.hpp tại validation_error và kiểm tra cách destructor cùng các hàm thành viên đặc biệt của nó tương tác với BOOST_DEFAULTED_FUNCTION. Sau đó, lần theo chi tiết quá trình khởi tạo sao chép trong throw_exception.hpp và đường đi của lời gọi trong detail/value_semantic.hpp. Công việc được xem là hoàn tất khi lỗi deprecated-copy-with-dtor đã được báo cáo được xử lý mà caller không cần tắt chẩn đoán.
