Update DeviceEntryViewModel transition source to transitionValue

- Only update deviceEntryIcon burnIn when AOD transitions update
by calling transitionInteractor.transitionValue.
- This CL also adds coroutine tracing for better traces.

Bug: 335673842
Flag: ACONFIG com.android.systemui.device_entry_udfps_refactor NEXTFOOD
Test: Check CoroutineContinuations in the perfetto trace for
DeviceEntryIconViewBinder#viewModel.burnInOffsets - there are a lot less
now when the device isn't transitioning to AOD.
