Do not show setup logs from createPerformanceLogger unless logs are enabled for it

Summary: This module logs helpful messages in `__DEV__` but it only logs actionable performance logs when the flag on top of the file is enabled. This diff changes those to only log when the toggle on top of the file is enabled as well.
