SF: Enforce a size limitation on SurfaceTracing

SurfaceTracing records operations of each frame update. It can exhaust
more than 2GB on memory heap in 5 mins if display keeps updating.
Enforce a size limitation on it and stop automatically to prevent memory
and storage from exhausting.

Note: Merge changes Iadbc1894, I3a3e499a

Bug: 115434782
Test: Trigger SurfaceTracing on/off repeatedly for thread-safe
Test: Enable SurfeaceTracing and let it disabled automatically
