Summary:
`_labelsForTags` is an array with string labels used only for local profiling, that we had to manually keep it in sync with `RCTPLTag`. Refactor so labels are assigned with switch instead.

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`.

Summary:
The `RCTBridge` contains numerous definitions of notification names, which we can observe in order to get insights into the React Native performance.
The Android implementation is a little different, such that you can listen for any of the [following](https://github.com/facebook/react-native/blob/master/ReactAndroid/src/main/java/com/facebook/react/bridge/ReactMarkerConstants.java) marker constants, simply by including the following code:
```java
ReactMarker.addListener(new ReactMarker.MarkerListener() {
Override
public void logMarker(ReactMarkerConstants name, Nullable String tag, int instanceKey) {
Log.d("ReactNativeEvent", "name: "+ name.name() + " tag: " + tag);
}
});
```
This will allow you to perform the necessary processing, calculations as required.

Summary:
Modules which call JS methods directly, or use `sendDeviceEventWithName:`, can trigger effects in JS without ever being referenced from the JS code. This breaks some assumptions in my earlier diff about when modules can be lazily loaded.
Pending a better solution, I've put explicit `init` methods in these modules to ensure they are eagerly initialized (the downside to this is that they'll still be initialized even if they are never used).

Summary: public
The `bridge.modules` dictionary provides access to all native modules, but this API requires that every module is initialized in advance so that any module can be accessed.
This diff introduces a better API that will allow modules to be initialized lazily as they are needed, and deprecates `bridge.modules` (modules that use it will still work, but should be rewritten to use `bridge.moduleClasses` or `-[bridge moduleForName/Class:` instead.
The rules are now as follows:
* Any module that overrides `init` or `setBridge:` will be initialized on the main thread when the bridge is created
* Any module that implements `constantsToExport:` will be initialized later when the config is exported (the module itself will be initialized on a background queue, but `constantsToExport:` will still be called on the main thread.
* All other modules will be initialized lazily when a method is first called on them.
These rules may seem slightly arcane, but they have the advantage of not violating any assumptions that may have been made by existing code - any module written under the original assumption that it would be initialized synchronously on the main thread when the bridge is created should still function exactly the same, but modules that avoid overriding `init` or `setBridge:` will now be loaded lazily.
I've rewritten most of the standard modules to take advantage of this new lazy loading, with the following results:
Out of the 65 modules included in UIExplorer:
* 16 are initialized on the main thread when the bridge is created
* A further 8 are initialized when the config is exported to JS
* The remaining 41 will be initialized lazily on-demand

Summary:
Fixes#1809
Even if a bridge has more than one root view, it's not supported by the js side
right now, and it will keep warning that those timespans had already been
recorded.
Summary:
@public
Add PerformanceLogger to keep track of JS download, initial script execution and
full TTI.
Test Plan:
The Native side currently calls `addTimespans` when it's finish initializing
with the six values (start and end for the three events), so I just checked it
with a `PerformanceLogger.logTimespans()` at the end of the function.
