Fix #24167: Timeline keyframes don't update when selecting objects from outliner

Based on patch from Alexander Kuznetsov. Own changes:
- Keyframes in timelime depends on active object, so timelime better be
  listeing to ND_OB_ACTIVE notifier rather than ND_OB_SELECT
- When scene is changing in this operator NC_WINDOW notifier would be send
  and the whole interface would be redrawed, so no need in ND_OB_ACTIVE in
  this case
