perf evlist: Add perf_evlist__to_front()
Add a function to move a selected event to the front of the list. This is needed because it is not possible to use the PERF_EVENT_IOC_SET_OUTPUT IOCTL from an Instruction Tracing event to a non-Instruction Tracing event. Thus the Instruction Tracing event must come first.
