Summary: JSON.stringify will convert a function to null, but folly::dynamic in the native code can't represent a JS function. Props do sometimes have functions, but don't permit them everywhere.

Summary:
We are removing `reactBridgeDidFinishTransaction`.
Why?
* It is a performance drain. Supporting this requires dispatching main-thread block on every single transaction complete;
* It has "too broad" non-conceptual semantic which encouraged using this as a "band-aid solution" for poorly designed components;
* It is conceptually incompatible with new approaches that we are trying to implement to optimize the render layer;
* It was deprecated for very long time.
This diff removes `reactBridgeDidFinishTransaction` from RCTScrollView component. As I mentioned, because of the semantic of `reactBridgeDidFinishTransaction` is extremely broad, it's hard to capture what exact case it should handle. Based on comments and existing logic, it seems it tight to `contentSize` property and the size of RCTScrollContentView.

Summary:
Because it is not simply flushing, it (in the future) is more complex process. And the names should represent logical meaning of the process, not particular implementation details.
It also nice to have unified terminology across our reactive UI frameworks.

Summary:
This change aims at replacing SYSTEM_ALERT_WINDOW/OVERLAY API being used for rendering dev support related views on Android (redbox, dev menu, green loading view) with API that does not require any special permission. The permission is still used for displaying perf monitor, although it is no longer requested at app startup but only when perf monitor gets enabled.
This change should not affect the way react native apps work in production environment as in release mode all dev support functionality is disabled.
There are two main reasons why requiring SYSTEM_ALERT/OVERLAY permission for displaying basic dev related windows is problematic:
1) On Android >=6 devices it is required that overlay permission is granted in device settings for apps being side loaded (not installed via play store which is usually the case for apps being developed). Although this setting is not available on some Android devices including Google's stock Android TV version. On such devices App cannot be granted rights to draw in system alert window which cases the app to crash (instead of showing a redbox or dev menu dialog)
2) Some Android device vendors have issues with implementation of `Settings.canDrawOverlays` that always return false (I've seen it on Xiaomi Redmi 4A with Android 6.1). This issue because of the following code in [ReactActivityDelegate.java#L90](1e8f3b1102/ReactAndroid/src/main/java/com/facebook/react/ReactActivityDelegate.java (L90)), results in the overlay permission settings screen popping up every time the app is launched even though the permission has been perviously granted which is extremely annoying. Since this change only require overlay permission for displaying perf monitor we no longer ask for it on startup but only when user switches perf monitor ON.
Test need to be performed on pre Android 6 and post Android 6 devices.
1. Run app with devserver off -> should result in redbox
2. Start packager with --reset-cache flag for the loading bar to be visible for some longer period of time. Then restart the app and see the loading bar show up
3. While the app is running, open dev menu, navigate to "dev settings", test "reload"
4. Modify JS app such that the app crashes, see it display redbox properly. Check if "reload" button works well from the redbox
5. Verify that "Show Perf Monitor" option works as expected. On Android >=6 re-install the app to see it ask for overlay permission at the moment when perf monitor option gets selected.
- SYSTEM_ALERT_WINDOW permission will no longer be required on Android to display Redbox
This change can break things for framework users who provide custom implementation of DevSupportManager interface on Android:
- **Who does this affect**: Owners of apps that use custom implementation of DevSupportManager interface on Android.
- **How to migrate**: Update `create` method of your `DevSupportManager`'s factory to take `ReactInstanceManagerDevHelper` type as a second argument instead of `ReactInstanceDevCommandsHandler`. The interface `ReactInstanceDevCommandsHandler` has been renamed to `ReactInstanceManagerDevHelper` but kept all the methods the same (new method got added). If you were calling one of three methods from `ReactInstanceDevCommandsHandler` interface (`onReloadWithJSDebugger`, `onJSBundleLoadedFromServer` and `toggleElementInspector`) you can call exact same methods directly on `ReactInstanceManagerDevHelper` instance that is being provided in exchange for `ReactInstanceManagerDevHelper `.
- **Why make this breaking change**:
This PR adds a new method to `ReactInstanceManagerDevHelper` called `getCurrentActivity`. In which case the prev name can no longer be justified. The activity is required for some of the DevSupportManager methods in order to start new dialogs and popups so that overlay permission isn't necessary.
- **Severity (number of people affected x effort)**:
Relatively small (perhaps Fb internally is using DevSupportManager abstraction to provide an alternative implementation but since it isn't documented I doubt anyone else uses it). Effort it very low as it boils down to updating uses of interface `ReactInstanceDevCommandsHandler` with `ReactInstanceManagerDevHelper` (all the methods in `ReactInstanceDevCommandsHandler` stays the same)

There are some errors I noticed after upgrading my flow version. I had them in my project, and they were also reported in #11655. These errors were ignored on master, but I went through and fixed them so the static analysis will work still.
After these changes, I receive no errors using flow `0.60.1` on latest master, or using `0.59` in my local project (which does not have the requisite ignores included).
- init a new project
`react-native init --version <path-to-repo> helloworld`
- add the flow binary
`yarn add -D flow-bin`
- run flow
`yarn flow`
- make sure there are no errors in the project.
```
No errors!
✨ Done in 23.60s.
