**Description:**
This PR changes the AST node construction code to use `.into()` or `::from()` to make changing the boxed-ness of the AST node easier. I used `ast-grep` to make large changes across codebase.

**Description:**
The original code separately records the usage of variables and checks if there is a closure. Changed to only record variables used in a closure.
**Related issue:**
- Closes https://github.com/swc-project/swc/issues/8010
**Description:**
Following development should follow babel/babel#16261 to avoid separate `WeakMap` for each individual private method
**Related issue:**
- Closes#8948.
**Description:**
This does not support
```js
class Foo extends Bar {
constructor() {
for (const i of [1]) {
setTimeout(() => {
console.log(this)
});
}
super();
}
}
```
but it does not seem to be used in a real-world code.
**Related issue:**
- Closes#8300
- Closes#8311
