Summary:
https://github.com/facebook/react-native/pull/25990 fixed the `forceUpdate` method to actually update the component, but caused the useEffect to fire on every render, causing continuous updates after dimensions changed (e.g. from rotation).
This reworks things a bit to be a bit simpler and more idiomatic so it's not quite as confusing, and fixes the bugs.
## Changelog
[General] [Fixed] - Fix useWindowDimensions hook firing continuously after dimensions change
Pull Request resolved: https://github.com/facebook/react-native/pull/26008
Test Plan:
Aparently the Mobile Home app supports rotation on iOS now, so replaced it's content with the first `DimensionsExample` and confirmed with logging that `useEffect` fires exactly once, on initial mount, but the view still updates as expected when rotated:

Summary:
Automatically provides and subscribes to dimension updates - super easy usage:
```
function MyComponent(props: Props) {
const {width, height, scale, fontScale} = useWindowDimensions();
return <Text ...
};
```
Only window for now - it's what people want 99% of the time, so we'll just shovel out a pit of success for them...
There are still cases where `Dimensions` is needed outside of React component render functions, like in GraphQL variables, so we need to keep the existing module.
