perf/core: Fix !CONFIG_PERF_EVENTS build warnings and failures
sparc64 runs into this warning:
include/linux/security.h:1913:52: warning: 'struct perf_event' declared inside parameter list will not be visible outside of this definition or declaration
which is escalated to a build error in some of the .c files due to -Werror.
Fix it via a forward declaration, like we do for perf_event_attr, the stub inlines
don't actually need to know the structure of this struct.
Fixes: da97e18458fb: ("perf_event: Add support for LSM and SELinux checks")
