Summary: With the introduction of TurboModules, it would be beneficial to measure the setup time of these modules, as we currently have it in place for NativeModules. The instantiation of the TMs occurs in the `RCTTurboModuleManager`. In order to successfully measure the time it took to setup the module, we need to ensure that we don't take into account cached modules. As such, we need to: 1. Check if module is in `_turboModuleCache` a. Start mark for `RCTPLTurboModuleSetup` tag if not found 2. Get the TM via `[self provideTurboModule:]` 3. Check if module is in `_turboModuleCache` a. Stop mark for `RCTPLTurboModuleSetup` if we did not find module in cache prior to **step 2** and if it's now present in the cache. b. Notify about setup time if the above is true. 4. Return TM ## Changelog [iOS] [Added] - Gain insights on the the turbo module setup times by observing `RCTDidSetupModuleNotification`. The userInfo dictionary will contain the module name and setup time in milliseconds. These values can be extracted via `RCTDidSetupModuleNotificationModuleNameKey` and `RCTDidSetupModuleNotificationSetupTimeKey`.
