Fixes https://github.com/vercel/next.js/issues/15188
`parseRelativeUrl` was used on urls that weren't always relative. It was used to generate a cache key, but we actually don't need these cache keys to be relative if the urls aren't relative.
Also took a look at the overall static data fetching logic and found a few things:
- [x] cache key is unnecessarily transformed through `prepareRoute`, we can just cache by resolved `dataHref` and remove that function. Pretty sure that `prepareRoute` was also introducing edge cases with `assetPath` and `delBasePath`
- [x] there is [a bug in the caching logic](ebdfa2e7a3/packages/next/next-server/lib/router/router.ts (L898)) that made it fail on the second visit: it should be `Promise.resolve(this.sdc[pathname])` instead of `Promise.resolve(this.sdc[dataHref])`. Also added a test for this
- [x] ~converted to async await to improve stacktraces and readability.~ I assumed this was fine since I saw some async/awaits in that file already but it seems to just blow up the size of the non-modern bundle.
- [x] extracted nested `getResponse` function and define it top level. this should improve runtime performance
- [x] convert `_getStaticData` and `_getServerData` to class methods instead of properties. Not sure why they were defined as properties but I think they belong on the prototype instead.
- [x] remove `cb` property from `fetchNextData`, it's unnecessary and makes the async flow hard to understand. The exact same logic can go in the `.then` instead.
- [ ] data fetching logic [retries on 5xx errors](ebdfa2e7a3/packages/next/next-server/lib/router/router.ts (L157)), but not on network level errors. It should also retry on those. It should also not retry on every 5xx, probably only makes sense on 502, 503 and 504. (e.g. 500 is a server error that I wouldn't expect to succeed on a retry)
The overall result also is a few bytes smaller in size
Next.js forcibly setting `module: 'esnext'` in `tsconfig.json` is necessary to prevent TypeScript from erroring on the following code:
```tsx
import dynamic from 'next/dynamic';
const A = dynamic(() => import('../A'));
```
```
ERROR in /Users/joe/Desktop/scratch/test-cjs/pages/index.tsx(5,25):
5:25 Dynamic imports are only supported when the '--module' flag is set to 'es2020', 'esnext', 'commonjs', 'amd', 'system', or 'umd'.
> 5 | const A = dynamic(() => import("../test"));
```
However, users may want to use one of the many other targets for better interoperability with projects that co-exist with their Next.js project (like `commonjs`).
When cross referenced with:
```
Option '--resolveJsonModule' can only be specified when module code generation is 'commonjs', 'amd', 'es2015' or 'esNext'.ts
```
That means we can permit any of these values:
```json5
parsedValues: [
ts.ModuleKind.ES2020,
ts.ModuleKind.ESNext,
ts.ModuleKind.CommonJS,
ts.ModuleKind.AMD,
],
```
This PR updates Next.js to allow those!

Fixes#15275
Chunks already have a normalized path.
Not sure if there are other chunks that require this change, I did a global search and didn't find similar cases.
Replace `url.parse` and `url.resolve` logic with whatwg `URL`, Bring in a customized `format` function to handle the node url objects that can be passed to router methods. This eliminates the need for `url` (and thus `native-url`) in core. Looks like it shaves off about 2.5Kb, according to the `size-limits` integration tests.
This adds handling for custom-routes with `basePath` to automatically add the `basePath` for custom-routes `source` and `destination` unless `basePath: false` is set for the route.

I noticed that the node_modules got passed by the ignore still because when chokidar identifies a ignore pattern is a glob it treats the glob as-is instead of appending `/**` to the glob
