fix(es/minifier): Remove hack for built-in class names (#8293) 
**Description:**

Regarding https://github.com/vercel/next.js/issues/55682, I made a mistake while investigating. I assumed it's `swcMinify`-only but it seems like `node-fetch` is fundamentally incompatible with our minification options.

I thought `node-fetch` works with terser, but it did not, and it **should not**. But as I thought `terser` works, I assumed that `terser` has a hack for `AbortSignal`. And that's how I fixed `swcMinify: true`. The correct fix is `keep_classnames: true` but it will result in +~10% bundle size bloat.
At first, I used the correct way (`keep_classnames: true`), but it resulted in the bundle size bloat, so I mimicked the hack of terser with https://github.com/vercel/next.js/pull/57904.

While working on other minification issues, I found that there's no such hack in `terser` and I need to remove the hack in the SWC minifier.
The repro in https://github.com/vercel/next.js/issues/55682 does not work with `swcMinify: false`, even with next@14. The problem of minifier and node-fetch was not exploited before `serverMinification: true`.

feat(es/minifier): Respect inline level and preserve native names (#8205) 
**Description:**

Note: Preserving native names is a hack, but it's used by `terser` and it's the only way to preserve the name of `class AbortSignal` while mangling without `keep_classnames: true`. We can special case `AbortSignal`, but let's just follow `terser`.

I did more investigation by monkey-patching the `next` package.
`.minify()` resolved without an exception.
It means that `.minify()` is producing an invalid ES code.

fix(es/minifier): Abort seq inliner if var is not fn_local or reassigned (#7804) 
**Description:**

It turns out that the original implementation of `infect`is incomplete
because it cannot cover function param, and the new implementation
introduced in #7772 is redundant because what
[terser](https://github.com/terser/terser/blob/master/lib/compress/tighten-body.js#L909C18-L909C28)
do is basically checking `fn_local`
