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.

So... candidates are

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`
