libcamera: bound_method: Manage BoundMethodPack through std::shared_ptr
The bound method arguments pack will need to be accessed by the method invoker in order to retrieve the method return value when using a blocking connection type. We thus can't delete the pack unconditionally in the bound method target thread. We also can't delete it unconditionally in the invoker's thread, as for queued connections the pack will be used in the target thread after the invoker completes. This shows that ownership of the arguments pack is shared between two contexts. As a result, manage it using std::shared_ptr<>.
