Changed the mangler to reuse variable names where possible.
This will reduce the code size as shorter variable names can be used in
more places. But requires global information and limits parallelism in a
single file and requires more memory.

This PR adds a `LatePeepholeOptimizations` pass for minifications that
don't interact with the fixed point loop.
While working on this I found a couple of cases where the previous fixed
point loop is not idempotent.
Adds `top_level` option which is similar to [terser's `toplevel`
option](https://terser.org/docs/cli-usage/#cli-mangle-options).

Pure refactor. Re-order imports for clarity:
1. `std`
2. External crates
3. `oxc_*` crates
4. Current crate `use crate::...`
5. Super `use super::...`
6. Local modules
This order is from "furthest away" to "closest". This makes it clearer to see what is coming from where.
`cargo +nightly fmt` (#7877) did a lot of the work, but unfortunately `rustfmt` does not have an option to (a) put workspace crates in a separate block from external crates and (b) move `mod` statements to after `use` statements.
Fix#7254
Changed all "raw" properties of literal types (if they have this property) to `Option<Atom>`.

I expect small performance regression.
But managed to improve the following case from react.developmement.js
```
oxc main ❯ diff before.js after.js
670c670
< if (!(dispatcher !== null)) throw Error("Invalid hook call. Hooks can only be called inside of the body of a function component. This could happen for one of the following reasons:\n1. You might have mismatching versions of React and the renderer (such as React DOM)\n2. You might be breaking the Rules of Hooks\n3. You might have more than one copy of React in the same app\nSee https://reactjs.org/link/invalid-hook-call for tips about how to debug and fix this problem.");
