perf evlist: Move perf_evlist__config() to a new source file

perf_evlist__config() must be moved to a separate source file to avoid
Python link errors when adding support for PERF_SAMPLE_IDENTIFIER.

It is appropriate to do this because perf_evlist__config() is a helper
function for event recording.  It is used by tools to apply recording
options to perf_evlist.  It is not used by the Python API.
