Set DisableLinesDuringVPClosing flag to true

Switches DisableLinesDuringVPClosing to be true to match the production stack, but does it by adding an invert parameter to the make_event_type algorithm to avoid the PyConf errors. Now the velo_closed event mask is created by inverting the velo open events in make_event_type instead of using the make_invert_event_list algorithm which is causing the PyConf errors in other CI tests. The invert parameter is implemented similarly to how @ahennequ proposed. Locally this passes the CI tests and has no impact on the throughput.
