Subject: [PATCH] Revert "fix(isolated_declarations): Always emit module
 declarations (#4911)" (#4916)

This reverts commit 0fb0b71f0d2615c39e7d7bcee764915aa76ce2d0.

test failed  https://github.com/oxc-project/oxc/actions/runs/10405198969/job/28815418191

We should only emit for
```ts
declare module "xx" {}
declare global {}
```

Do not emit for
```ts
module x {}
declare module x {}
```
