perf annotate: Add itrace options support

The "auxtrace_info" and "auxtrace" functions are not set in "tool" member of
"annotate". As a result, perf annotate does not support parsing itrace data.

Before:

  # perf record -e arm_spe_0/branch_filter=1/ -a sleep 1
  [ perf record: Woken up 9 times to write data ]
  [ perf record: Captured and wrote 20.874 MB perf.data ]
  # perf annotate --stdio
  Error:
  The perf.data data has no samples!

Solution:

1. Add itrace options in help,
2. Set hook functions of "id_index", "auxtrace_info" and "auxtrace" in perf_tool.

After:

  # perf record --all-user -e arm_spe_0/branch_filter=1/ ls
  Couldn't synthesize bpf events.
  perf.data
  [ perf record: Woken up 1 times to write data ]
  [ perf record: Captured and wrote 0.010 MB perf.data ]
  # perf annotate --stdio
