perf evswitch: Introduce init() method to set the on/off evsels from the command line

Another step in having all the boilerplate in just one place to then use
in the other tools.

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.
