[cxx-interop] Reapply implicitly defined copy and move constructors

[susmonteiro]

This patch reapplies #84646 and #85236:

If a C++ type doesn't have a user provided copy constructor, Clang will declare one implicitly, unless one of its fields is not copy-constructible. Clang assumes that any std::vector is always copy-constructible, including a std::vector of a non-copy constructible type. So, let's use the CxxValueSemantics implemented in #84340 to figure out if we should ask Clang to define the copy constructor for such types.

This also includes types that have a defaulted, user-provided copy constructor.

These patches were reverted (#85331) because they triggered a cycle in the CxxValueSemantics requests. After #85485, these cycles have been prevented and we can safely re-land those patches.
