At the moment, initialization path is using test_cpu_cap(&boot_cpu_data),
to detect PT, which is just open coding boot_cpu_has(). Use the latter
instead.

As per AUX buffer management requirement, AUX output has to happen between
pmu::start and pmu::stop calls so that perf_event_stop() actually stops it
and therefore perf can free the AUX data after it has called pmu::stop.
This patch moves perf_aux_output_{begin,end} from pt_event_{add,del} to
pt_event_{start,stop}. As a bonus, we get rid of pt_buffer_is_full(),
which is already taken care of by perf_aux_output_begin() anyway.

Now that all functionality has been moved to arch/x86/events/, move the
perf_event.h header and adjust include paths.
