Summary: This diff adds performance loggers for Fabric in Android to be able to compare current version or RN with Fabric This is the summary of Points and Annotations: - **UIManager_CommitStart**: time that React starts the commit (react tree is ready to start rendering in native) - **UIManager_LayoutTime**: this is the time it takes to calculate layout in yoga - **UIManager_FabricFinishTransactionTime**: Time it takes transform "C++ mutationInstructions" into "Java MountItems" and cross boundaries from C++ to Java (including serialization of data) (THIS IS ONLY FABRIC) - **UIManager_DispatchViewUpdates**: time right before RN moves the mount operations to the Queue that is going to be processed in the next tick UI thread - **UIManager_BatchRunStart**: time right before the mountItems are going to be process in the UI Thread - **UIManager_BatchedExecutionTime**: time it took to run batched mountItems (usually layout and prop updates on views) - **UIManager_NonBatchedExecutionTime**: time it took to run non-batched mountItems (usually creation of views) Reviewed By: fkgozali Differential Revision: D13838337 fbshipit-source-id: 0a707619829e7d95ce94d9305ff434d1224afc46
