cameraserver: Make trace points in HFR code paths optional.
Per processCaptureResult save 4 trace point costs -> approximately 2%of 4ms budget.
Save 2 trace points per processCaptureRequest call.
[assuming each trace point costs around 10us]
Bug: 155910869
Test: Try HFR; record perfetto trace, make sure trace points opted out
don't appear
