Subject: [PATCH v9 14/27] x86/resctrl: Fix types in resctrl_arch_mon_ctx_alloc() and free stubs

resctrl_arch_mon_ctx_alloc() and resctrl_arch_mon_ctx_free() take an enum
resctrl_event_id. This in turn requires the enum to be defined in
resctrl_types.h so that it is accessible to asm/resctrl.h.

The x86 stubs take an int. Fix that.
