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";

```
