#8169 added `if self.in_fixed_loop` in `try_compress_property_key`. Because `exit_property_key` was not called for `PeepholeOptimizations`, `try_compress_property_key` was never called.

This PR makes OXC behave exactly like `tsc`, with a little test case.

fix(transformer/class-properties): correctly resolve private fields pointing to private methods ( #8042 )
...
We don't transform private methods yet, but in class properties transform, still need to record private methods that classes have, so can correctly resolve private fields.
```js
class Outer {
#foo = 123;
method() {
class Inner {
#foo() {}
// Refers to `Inner`'s `#foo` method, not `Outer`'s `#foo` property
prop = this.#foo;
}
}
}

Add failing test for nullish coalescing operator. The output is correct, but temp var is created in wrong scope.
My guess is that it needs to use `current_hoist_scope_id`, not `current_scope_id`.
This test from class properties also shows the same problem: ac097e9160/tasks/transform_conformance/snapshots/oxc.snap.md (L20-L35)

fix(transformer/class-properties): run other transforms on static properties, static blocks, and computed keys ( #7982 )
...
Large re-architecting of class properties transform. Split transform into 3 phases:
1. Transform instance properties when entering class.
2. Transform private fields during traversal of class body.
3. Transform static properties and static blocks when exiting class.
This ensures that code which has to be moved outside of the class (static property initializers, static blocks, computed keys) can get transformed by other transforms before they're moved out.
Also fixes a problem where we previously registered private properties too early - on entering the class, rather than the class *body*, so private fields in `extends` clause of a nested class were misinterpretted.

refactor(semantic): change Bindings to a plain FxHashMap ( #8019 )
...
`IndexMap` was needed for the insertion order requirement in mangler.
Bindings (symbol ids) are monotonically increasing by binding
positions, which means we can get insertion order by sorting the symbol ids in
mangler.
