perf evswitch: Move struct to a separate header to use in other tools Now that we see that the simple userspace-based "slicing" of events using delimiter events ("markers") works, lets move it to a separate header to make it available to other tools, next step will be having the switch on/off check done at the PERF_RECORD_SAMPLE processing function moved too.

perf evswitch: Move switch logic to use in other tools Now other tools that want switching can use an evswitch for that, just set it up and add it to the PERF_RECORD_SAMPLE processing function.
