## What is the current behavior?
<!-- Please describe the current behavior that you are modifying. -->
Ionic React projects using `@types/react@18.2.43` or greater will run
into a type-check error on build with `IonRouterOutlet` and potentially
other components:
```
Property 'placeholder' is missing in type '{ children: Element[]; }' but required in type 'Pick<IonRouterOutlet & { basePath?: string | undefined; ref?: Ref<any> | undefined; ionPage?: boolean | undefined; } & IonicReactProps & Omit<...>, "color" | ... 254 more ... | "ionPage">'.
```
Definitely typed decided to make a breaking type change in a patch
release:
b954269038
## What is the new behavior?
<!-- Please describe the behavior or changes that are being added by
this PR. -->
- Patches the type to allow for compatibility between React v16, 17 and
18.

### Testing
1. Create a new Ionic react project with the "list" template.
2. Run `npm run build`
3. Observe: Exception posted above
4. Install the dev-build
5. Run `npm run build`
6. Observe: No exception, build passes
7. You can additionally serve the app to verify no runtime
exceptions/broken behavior.

This is part of my work for hack day, but I wanted to tackle the
following problems:
1. There is no easy way to have angular, angular-server, vue,
vue-router, react, and react-router automatically recompile when you
make a change. Right now you have to manually run `npm run build` every
time you make a change.
## What is the new behavior?
<!-- Please describe the behavior or changes that are being added by

- Adds `npm run build.watch` to let developers easily watch for changes
in each project.

The vue, vue-router, react, and react-router packages are bundled with a
version of rollup that are 2 major versions out of date.
## What is the new behavior?
<!-- Please describe the behavior or changes that are being added by
this PR. -->
- Update deps to rollup 4 and made any necessary changes as a result of
breaking changes
- Removed the react projects old treeshaking script. The rollup dep used
was incompatible with Rollup 4, and the script didn't work to begin
with.
- Removed the source maps and resolve plugins. These did not make any
difference in the final result, and source maps are still included in
the final build.
- Removed a PURE annotation from an import. Rollup 4 warns about this,
and this PURE annotation does not seem to be needed since every import
in this file uses "createReactComponent" to begin with.

Rollup has a plugin to handle TypeScript compilation that we are not
using. As a result, we are maintaining unnecessary infrastructure such
as compiling to `dist-transpiled`(TS to JS) and then compiling the
results to `dist` (JS files to bundled code).
## What is the new behavior?
<!-- Please describe the behavior or changes that are being added by
this PR. -->
- Vue, Vue Router, React, and React Router now make use of the Rollup
Typescript plugin to handle TypeScript compilation for us. This lets us
remove the `dist-transpiled` directory altogether and the manual `tsc`
invocation.

Developers should not see any changes in how they consume Ionic. This
just hands the TypeScript compilation step off to the Rollup plugin.

## What is the current behavior?
<!-- Please describe the current behavior that you are modifying. -->
Ionic lifecycle hooks do not execute a cleanup function when the
underlying `useEffect` is unmounted.
```ts
useEffect(() => {
return () => {
console.log('cleanup'); // called
};
});
useIonViewWillEnter(() => {
return () => {
console.log('cleanup'); // never called
};
});
```
Ionic's implementation registers the lifecycle callback to be handled at
a later time, by the page managers. However, it does not keep a
reference to the returned callback, so it cannot execute it when the
`useEffect` is unmounted.
## What is the new behavior?
<!-- Please describe the behavior or changes that are being added by

- Ionic lifecycle hooks execute dev-specified cleanup functions

## What is the current behavior?
<!-- Please describe the current behavior that you are modifying. -->
While debugging #28186, Maria and I identified that Ionic's lifecycle
event listeners (`ionViewWillEnter`, etc.) were being registered
multiple times on the same `.ion-page` element. This resulted in
problematic behavior, where a user's implementation of our lifecycle
hooks, would execute their callback multiple times.
```ts
useIonViewWillEnter(() => {
// This is called 2x for every time the `ionViewWillEnter` event is emitted (in React 18, dev mode)
console.log('hello world');
});
```
When the Ionic lifecycle event listeners are registered in React, we
bind the scope of the class to the callback function. When removing the
event listener we additional use the `.bind` syntax.
```tsx
componentDidMount() {
element.addEventListener('ionViewWillEnter', this.ionViewWillEnter.bind(this));
}
componentWillUnmount() {
// This creates a new instance of the function to remove! It doesn't remove the original event listener.
element.removeEventListener('ionViewWillEnter', this.ionViewWillEnter.bind(this));
}
```
The `.bind` method returns a new instance of the function. This means in
the implementation we are creating a new instance of the function when
both adding and removing the event listener - resulting in the
`removeEventListener` to never remove the original event listener.
This behavior only occurred in React 18 in dev mode, as a result of the
mount/unmount behavior running 2x for `useEffect` hooks.
## What is the new behavior?
<!-- Please describe the behavior or changes that are being added by
this PR. -->
- Ionic lifecycle event listeners are removed from element references
when they are unmounted.
- User's lifecycle callback methods are only invoked once per event
emission.
