Fix crash from asynchronous GPU metrics
Making the scope more accurate that only acquire the lock when trying
to access frame info in FrameInfoVisualizer, then make it irrelevant
to the real draw operation.
Bug: 317995179
Test: 1.going to developer options
2. swapping the "profile hwui" option from "none" to "bars"
and back a couple times, no crash
