perf script python: Add more PMU fields to event handler dict

When doing pmu sampling and then running a script with perf script -s
script.py, the process_event function gets dictionary with some fields
from the perf ring buffer (like ip, sym, callchain etc).

But we miss quite a few fields we report now, for example, LBRs, data
source, weight, transaction, iregs, uregs, etc.

This patch reports these fields for perf script python processing.

  New keys/items:
  ---------------
  key  : brstack
  items: from, to, from_dsoname, to_dsoname, mispred,
         predicted, in_tx, abort, cycles.

  key  : brstacksym
  items: from, to, pred, in_tx, abort (converted string)

  key  : datasrc
  key  : datasrc_decode (decoded string)
  key  : iregs
  key  : uregs
  key  : weight
  key  : transaction

  v2:
  ---
  Add new fields for dso.
  Use PyBool_FromLong() for mispred/predicted/in_tx/abort

Committer notes:

!sym->name isn't valid, as its not a pointer, its a [0] array, use
!sym->name[0] instead, guaranteed to be the case by symbol__new.

This was caught by just one of the containers:
