fix(codegen): escape sources for empty import specifiers (#25586)

## Summary
- Route empty named-import sources through the shared string-literal printer.
- Cover quote and newline escaping, including minified quote selection.

Given:
```ts
import {} from 'h"i'
```

Before it would be printed as:
```ts
import {} from "h"i" // missing escape of `"` or should be using `'` quotes
```

After:
```ts
import {} from 'h"i'
```
