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`.
