Time duration blocked on dequeueBuffer for stuffing recovery

Start buffer stuffing recovery only when severely buffer stuffed.
Determined based on how long BBQ waits on buffer release. Waits
shorter than this may simply be false positives for buffer stuffing
recovery due to timing and should be ignored.

Bug: b/294922229
Test: Manually check perfetto traces, presubmit, SysUi performance tests
Flag: android.view.flags.buffer_stuffing_recovery
