Are we recreating the graph each time?

We create this structure to add graph nodes to it. Once the structure is complete, we instantiate the actual graph with a call like :
cudaGraphInstantiate(&upd_bnd_exec, upd_graph, NULL, NULL, 0);
This is done once per graph in the setup function inside constructor by calling either create_bounds_update_graph() or create_constraint_slack_graph().

This PR removes cuda graph capture from load balanced bounds strengthening to address crashes encountered in the constructor. The cuda graph is instead created manually. Fixes #219
