Configure baseline profiles in the baselineProfile lambda (#1060)

* Configure baseline profiles in the baselineProfile lambda

* This is the correct and easiest way to set up baseline profiles correctly.
  * See b/313428246 for more context.
* Handle empty topics during baseline profile generation
* Revert to API 33 GMD and fail empty screen tests
* Rename withChildren to noChildren for better legibility
* Remove unused log tags
* Update benchmark and metrics versions
* 🤖 Updates baselines for Dependency Guard
