Subject: [PATCH v9 13/27] x86/resctrl: Move enum resctrl_event_id to resctrl.h

A previous patch moved enum resctrl_event_id into a smaller header file,
resctrl_types.h, so that architectures could use these types in their
definitions of asm/resctrl.h. Specifically this was for
resctrl_arch_get_cdp_enabled() and resctrl_arch_set_cdp_enabled().

Those two functions are no longer inlined by any architecture, so
the enum can be moved to resctrl.h.
