Summary:
When the AppState module is initialized, it subscribes to the `appStateDidChange` event and sends an async native method call to the AppState native module. There is a small race condition window where the native module can read the current app state as `uninitialized` before calling the JavaScript callback, and then be interrupted by the underlying mechanism to trigger the `appStateDidChange` event. If the `appStateDidChange` event is processed before the JavaScript callback, the resulting value of `AppState.currentState` will be invalid.
FixesMicrosoft/react-native-windows#1300
(Write your test plan here. If you changed any code, please provide us with clear instructions on how you verified your changes work. Bonus points for screenshots and videos!)
I simulated (over-exaggerated) the race condition by injecting "thread sleep" calls in the native method call and the native mechanism for updating the app state.
I then ran the AppStateExample in the RNTester and found that the current app state was set to `uninitialized`, as opposed to the expected value of `active`.
Once I made this JavaScript change, the over-exaggerated race condition no longer resulted in an invalid app state.

Summary:
118e88393e broke autodoc generation because autodoc isn't smart enough to understand some patterns.
I'm working around it by using the same trick as this file was using previously: reassigning the class variable.
Similarly, using a property initializer produces bad output so I had to remove it:

Summary:
Attempt to fix#7919.
Currently, if the app is launched into the background and you read `AppState.currentState` too soon, you will see the value `'active'` instead of `'background'`. This is because the default value of `AppState.currentState` is hardcoded to be `'active'` and it is initialized with the actual value asynchronously.
This attempts to fix the bug by having the `RCTAppState` module provide the initial state as a module constant.
As noted in #7919, it looks like this fix was already tried and reverted with 0fb3d8de83. zjj010104, hedgerwang, nicklockwood -- can you explain why? I would very much like to get this bug fixed. Nobody has followed up on the issue I filed so I decided to just go ahead and make a PR with my best guess at a fix.
**Test plan (required)**
Built a small app as described in the repro steps for #7919 and verified that, when the app is launched into the background, `init currentState: background` is printed. Also verified that `i
