perf(es/minifier): Do not visit var init multiple times (#9039) 
**Description:**

I mistakenly introduced a performance regression with https://github.com/swc-project/swc/pull/9032. It makes the minifier visit the initializer of variables multiple times - once while normal visiting and once in `hoist_props_of_vars`. This PR fixes it.

fix(es/minifier): Visit RHS while hoisting properties (#9032) 
**Description:**

Handles 

```js
var FRUITS = { MANGO: "mango" }, getMangoLabel = (label) => label[FRUITS.MANGO];
```

while hoisting properties. In the code above, the initializer of the second variable declarator should be visited after hoisting the first variable declarator. Otherwise `FRUITS.MANGO` cannot be handled.

 - Closes #9030

feat(es/minifier): Detect TypeScript enum initialization pattern (#8986) 
**Description:**

We can optimize
```js
var Foo;
Foo || Foo = {};
```

This code looks strange, but 
```ts
enum Foo {
    a = 1,
    b = 2,
}
```

transpiles to

```js
var Foo;
(function(Foo) {
    Foo[Foo["a"] = 1] = "a";
    Foo[Foo["b"] = 2] = "b";
})(Foo || (Foo = {}));

```

and after minification it becomes

```js
var Foo, Foo1;
(Foo1 = Foo || (Foo = {}))[Foo1.a = 1] = "a", Foo1[Foo1.b = 2] = "b";

```

fix(es/jest): Handle @jest/globals (#8994) 
**Description:**

- We have two `jest` pass. One in `@swc/core` (via _hidden.jest flag), and one in the plugin. This PR fixes only the core one.

However, the linked issue is wrong because the code tries to break the rules of ESM specification. So, although this PR closes the issue, the final form is not the issue the author wanted.

**Related issue:**
