Subject: [PATCH] [libc++] Add default copy ctor to "__chrono/exception.h"

After PR#90394, "__chrono/exception.h" will trigger
"deprecated-copy-with-user-provided-dtor" warning on Windows x64
runtime testing with ToT Clang. This patch addresses this issue by
explicitly adding those default copy ctors.
