Fix SWC's auto_cjs handling (#46448)
Closes #43732.

We currently detect if a module is CJS by look through all string tokens to see if any contains `"__esModule"`. That causes `console.log('__esModule')` being detected as CJS accidentally. This PR changes to detect these cases:
- `module.exports`
- `exports.__esModule` (e.g. `exports.__esModule = true`)
- `Object.defineProperty(exports, "__esModule", ...)` 

Although this solution isn't perfect, it's much more reliable that the current one already.

Note that this also fixes a bug for `@vercel/og` that although `satori`'s ESM module is imported, it still has the `__esModule` string inside, introduced by bundling its vendors.
