Moved app-dir path params parsing logic from `useParams` to `AppRouter`.
This allows for the use of `PathParamsContext` in the `useParams` hook
for both pages and app routers. In addition, this allows for memoization
of the layout tree which fixes undesired re-renders of the `useParams`
hook.
Fixes [#58788](https://github.com/vercel/next.js/issues/58788)
Closes NEXT-2434

### `useSearchParams`
server router's query includes both search params and path params, this PR eliminate the path params from `useSearchParams` to make it aligned between app router and pages router
### `useParams`
For pages, we extract the params keys with `getRouteRegex`, and pick them out from `router.query`
Fixes#54242
Closes NEXT-1536
This updates our `moduleResolution` to `bundler` as this matches our heuristics much more closely so is more accurate. This shouldn't be a breaking change is it should be compatible with our previous default.

## What?
Removes `experimental.appDir` this was leftover from when I flipped the
switch.
Kept the config file as in the future we might add future flags and
such. It also helps that it has the types comment included so you always
get types.

### What?
Adds `useParams` to read the canonical parameters.
```tsx
'use client'
import { useParams } from 'next/navigation'
export default function Page() {
const { id } = useParams()
return (
<div>
<div id="param-id">{id}</div>
</div>
)
}
```
### Why?
Allows for accessing segment parameters for the entire page.
### How?
It uses a similar resolving of `useSelectedLayoutSegments` which resolve `children` and if `children` is not available the first available parallel route instead.
Closes NEXT-99
