SystemUI: Replace all usages of runBlocking with runBlockingTraced

- We want to be able to trace each call of runBlocking,
  as per the upcoming runBlocking deprecation
- This CL (in part with ag/33097585), replaces all usages
  with runBlockingTraced from tracinglib

Bug: 409734069
Flag: EXEMPT uses traceTag - TRACE_TAG_APP
Test: Manual - compile and run SystemUI
