Issue:
Wrong typescript mixed enum code generation
### Describe the bug

There seems to be a bug while generating code for mixed enums in typescript. TS and Babel agree on the code generation, but SWC differs.

### Input code

```typescript
enum A {
    X1,
    X15 = "x15",
    X2 = 6,
}
```


### Config

```json
N/A I just used the playground
```


### Playground link

https://play.swc.rs/?version=1.2.144&code=H4sIAAAAAAAAA0vNK81VcFSo5lIAgghDHShtqmCroFRhaKoEFTAC8s10uGoB7sSgdi8AAAA%3D&config=H4sIAAAAAAAAA0WNSwrDMAxE76J1ts0id%2BghjKsEF%2F%2FQKBBjfPfawSU7aebpqdIXlrZK2QhYxoQS1Vy0kZbMsOKy0kKKHu3Gg1tfjBysHWG8eudTAs92oeCi28sw2RSyMPBUJh7%2BT7YuCulzjqDez27hSu1xzDuH9wRVTm4%2FOkwQUrUAAAA%3D

### Expected behavior

[TS playground](https://www.typescriptlang.org/play?#code/KYOwrgtgBAglDeAoKKoA0CMAaZrMFYoBeKAIgA8N9SdV0AmYqANhwF9Eg) and [babel playground](https://babeljs.io/repl#?browsers=defaults%2C%20not%20ie%2011%2C%20not%20ie_mob%2011&build=&builtIns=false&corejs=3.21&spec=false&loose=false&code_lz=KYOwrgtgBAglDeAoKKoA0CMAaZrMFYoBeKAIgA8N9SdV0AmYqANhwF9Eg&debug=false&forceAllTransforms=false&shippedProposals=false&circleciRepo=&evaluate=false&fileSize=false&timeTravel=false&sourceType=module&lineWrap=true&presets=env%2Creact%2Cstage-2%2Ctypescript&prettier=false&targets=&version=7.17.6&externalPlugins=&assumptions=%7B%7D) agree on this generated code:
```
var A;

(function (A) {
  A[A["X1"] = 0] = "X1";
  A["X15"] = "x15";
  A[A["X2"] = 6] = "X2";
})(A || (A = {}));
```


### Actual behavior

but SWC instead generates:
```
var A;
(function(A) {
    A[A["X1"] = 0] = "X1";
    A[A["X15"] = "x15"] = "x15";
    A[A["X2"] = 6] = 6;
})(A || (A = {}));
```

note in particular the generation of the string enum part, `A["X15"] = "x15";` vs `A[A["X15"] = "x15"] = "x15";`
