perf stat: Define a structure for per-thread shadow stats
Perf has a set of static variables to record the runtime shadow metrics
stats.
While if we want to record the runtime shadow stats for per-thread, it
will be the limitation. This patch creates a structure and the next
patches will use this structure to update the runtime shadow stats for
per-thread.
