fs/resctrl: Introduce event configuration field in struct mon_evt
When supported, mbm_event counter assignment mode allows the user to configure
events to track specific types of memory transactions.
Introduce an evt_cfg field in struct mon_evt to define the type of memory
transactions tracked by a monitoring event. Also add a helper function to get
the evt_cfg value.
