Camera: Avoid device sync during capture if possible

Currently we always sync using the latest request id
before standard capture. The purpose is to avoid
sending triggers and 3A mode settings out of sync to
Hal. However during regular capture the precapture
trigger is not always used so we should be able to
skip the device sync in this case. This can enable
capture requests to arrive in Hal with one preview
frame earlier.
