perf: Add pmu specific data for perf task context
Introduce a new flag PERF_ATTACH_TASK_DATA for perf event's attach
stata. The flag is set by PMU's event_init() callback, it indicates
that perf event needs PMU specific data.
The PMU specific data are initialized to zeros. Later patches will
use PMU specific data to save LBR stack.
