Restructure perf list so that it uses callbacks to print events and
metrics. Use the callbacks to implement json output. In the process
add documentation to pmu.h, avoid some sorting of events, fix some
command line and output bugs.

v3. Removes is_hybrid from perf_pmu as suggested by Kan Liang.
    ScaleUnit is added to the json output as suggested by
    Weilin Wang. Some comments are also improved.
v2. Address feedback from Adrian Hunter and make kernel-doc work.
