So that we don't have to pass it around to the several methods that needs it, simplifying usage. There is one case where we don't have the thread/cpu map in advance, which is in the parsing routines used by top, stat, record, that we have to wait till all options are parsed to know if a cpu or thread list was passed to then create those maps. For that case consolidate the cpu and thread map creation via perf_evlist__create_maps() out of the code in top and record, while also providing a perf_evlist__set_maps() for cases where multiple evlists share maps or for when maps that represent CPU sockets, for instance, get crafted out of topology information or subsets of threads in a particular application are to be monitored, providing more granularity in specifying which cpus and threads to monitor.
