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`.

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`


**Related issue:**

 - Closes #7784

feat(es/minifier): Clone trivial literals in sequential inliner (#6005)
**Description:**

As our minifier is two-pass by default, this is enough.

At the first pass, we inline all numeric literals using sequential inliner, and minifier can then inline constants correctly in the second pass.

feat(es/minifier): Inline lazily initialized variables (#5737)
Safety:

For a function-local variable, an expression with side-effects would be a call, including an indirect one with a member expression.

 - If the call is function-local, it will be analyzed by the analyzer and inliner will not work.
 - If the call is not a function-local one, it cannot modify the local variable.

feat(es/resolver): Use different syntax context for unresolved refs (#4436)
- We don't need a list of bindings to check if an identifier is unresolved.
 - Checking if an identifier is unresolved is now one CPU instruction.
   - Previously it was one hashmap operation.
 - This PR also improves performance, by removing the hashmaps mentioned above.
