The process_event python hook receives a dict with most perf_sample
entries.

Other handlers (e.g. trace_unhandled, python_process_tracepoint) predate
the introduction of this dict and do not receive it. This patch series
adds the dict to all handlers, aiming to unify the information passed to
them.

This change adds an additional argument to the affected handlers. To
keep backwards compatibility (and avoid unnecessary work), do not pass
the aforementioned dict if the number of arguments signals that handler
version predates this change.

In addition, provide time_enabled, time_running and counter value in the
perf_sample dict.

  perf script python: Allocate memory only if handler exists
  perf script python: Refactor creation of perf sample dict
  perf script python: Add sample_read to dict
  perf script python: Add perf_sample dict to tracepoint handlers
  perf script python: Generate hooks with additional argument
