"Mac_android hot_mode_dev_cycle__benchmark" is currently failing in devicelab_staging. It is not running in either cocoon or luci devicelab prod (and thus not blocking the tree) https://ci.chromium.org/ui/p/flutter/builders/prod/Mac_android%20hot_mode_dev_cycle__benchmark/36/overview

Brief summary of what happened:

• due to a mistake during the cocoon -> luci devicelab migration, 100% of the mac/android bots were moved from cocoon to devicelab_staging, and thus the cocoon builds were not running and thus failing tests did not make the tree red.
• there were three failing tests that were not noticed by the framework gardener. the three tests were Mac_android microbenchmarks, Mac_android hot_mode_dev_cycle__benchmark and Mac_android android_semantics_integration_test.
• 444c954 was landed to intentionally fail hot_mode_dev_cycle_macos_targetbenchmark in order to explicitly close the tree until either the tests are fixed or the devicelab tests are migrated to devicelab prod, in which case they will show up on the build dashboard.
• 75dc45a was landed to fix Mac_android hot_mode_dev_cycle__benchmark
• The revert cecb7f3 was landed to fix Mac_android android_semantics_integration_test (the initial commit landed right after the migration of the test from cocoon to devicelab_staging)
• the mac/android tests have been migrated to devicelab prod luci group.
• 3c27a56 landed to add the LUCI mac/android tasks to the build dashboard.

Things that need to happen for this issue to be closed:

• Mac_android hot_mode_dev_cycle__benchmark passes green build
• Mac_android android_semantics_integration_test fixed and passes green build
• Mac_android microbenchmarks passes green build
• framework prod_builders.json file updated to include mac/android tasks PR
• the intentional fail in hot_mode_dev_cycle_macos_targetbenchmark removed PR
