Summary:
{emoji:26a0} This is a follow up to https://github.com/facebook/react-native/issues/25425 -- which isn't merged yet… See https://github.com/facebook/react-native/pull/25919/files/2a286257a6553a80a34e2b1f1ad94fc7bae36ea3..125aedbedc234c65c8d1b2133b79e926ad6cf145 for actual diff
Currently, StatusBar native module manages the status bar on iOS globally, using `UIApplication.` APIs. This is bad because:
- those APIs have been deprecated for 4 years
- Apple really, really wants you to have an explicitly defined view controller, and control the status bar there
- it [breaks external native components](https://github.com/facebook/react-native/issues/25181#issuecomment-506792819)
- it's [not compatible with iPadOS 13 multi window support](https://github.com/facebook/react-native/issues/25181#issuecomment-506690818)
for those reasons I we should transition towards view controller-based status bar management.
With that, there is a need to introduce a default React Native root view controller, so I added `RCTRootViewController`. Using it is completely opt-in and there is no breaking change here. However I believe this should be a part of the template for new RN iOS apps.
Additionally, I added `RCTRootViewControllerProtocol` with hooks needed for RCTStatusBarManager to control the status bar. This means apps that want to have total control over their view controller can still opt in to react native VC-based status bar by conforming their root view controller to this protocol.
## Changelog
[iOS] [Added] - Added `RCTRootViewController` and `RCTRootViewControllerProtocol`
[iOS] [Fixed] - `UIViewControllerBasedStatusBarAppearance=YES` no longer triggers an error as long as you use `RCTRootViewController`
[iOS] [Fixed] - Status bar style is now correctly changed in multi-window iPadOS 13 apps if you use `RCTRootViewController` and set `UIViewControllerBasedStatusBarAppearance=YES`

Test Plan: - Open RNTester → StatusBar → and check that no features broke

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/28058
I'm taking the first step towards supporting iOS 13 UIScene APIs and modernizing React Native not to assume an app only has a single window. See discussion here: https://github.com/facebook/react-native/issues/25181#issuecomment-505612941
The approach I'm taking is to take advantage of `RootTagContext` and passing it to NativeModules so that they can identify correctly which window they refer to. Here I'm just laying groundwork.
- [x] `Alert` and `ActionSheetIOS` take an optional `rootTag` argument that will cause them to appear on the correct window
- [x] `StatusBar` methods also have `rootTag` argument added, but it's not fully hooked up on the native side — this turns out to require some more work, see: https://github.com/facebook/react-native/issues/25181#issuecomment-506690818
- [x] `setNetworkActivityIndicatorVisible` is deprecated in iOS 13
- [x] `RCTPerfMonitor`, `RCTProfile` no longer assume `UIApplicationDelegate` has a `window` property (no longer the best practice) — they now just render on the key window
Next steps: Add VC-based status bar management (if I get the OK on https://github.com/facebook/react-native/issues/25181#issuecomment-506690818 ), add multiple window demo to RNTester, deprecate Dimensions in favor of a layout context, consider adding hook-based APIs for native modules such as Alert that automatically know which rootTag to pass
## Changelog
[Internal] [Changed] - Modernize Modal to use RootTagContext
[iOS] [Changed] - `Alert`, `ActionSheetIOS`, `StatusBar` methods now take an optional `surface` argument (for future iPadOS 13 support)
[iOS] [Changed] - RCTPresentedViewController now takes a nullable `window` arg
[Internal] [Changed] - Do not assume `UIApplicationDelegate` has a `window` property
Pull Request resolved: https://github.com/facebook/react-native/pull/25425
Test Plan:
- Open RNTester and:
- go to Modal and check if it still works
- Alert → see if works
- ACtionSheetIOS → see if it works
- StatusBar → see if it works
- Share → see if it works

Summary:
Adds requiresMainQueueSetup YES to top 16 components warning to help clean up the console. This should cut down ~50% of native warnings from React Native.
This should not change any behavior, just make the existing behavior explicit.
