timer_migration: Add tracepoints The timer pull logic needs proper debugging aids. Add tracepoints so the hierarchical idle machinery can be diagnosed.

timers/migration: Rename childmask by groupmask to make naming more obvious childmask in the group reflects the mask that is required to 'reference' this group in the parent. When reading childmask, this might be confusing, as this suggests, that this is the mask of the child of the group. Clarify this by renaming childmask in the tmigr_group and tmc_group by groupmask.
