transformer: incorrect sourcemap for multiline imports

[sapphi-red]

The specifier part isn't mapped correctly.

reproduction using transform function exposed from rolldown: https://stackblitz.com/edit/github-xv4yss-hhyuz3j3?file=build.mjs

I used rolldown 2e368ff which uses OXC 0.49.0.
This does not reproduce with rolldown 06372d4 which uses OXC 0.48.2 (visualizer).

I found this when upgrading rolldown in rolldown-vite.

It seems it's not only for multiline ones. The sourcemap is incorrect for import depCjs from '@vitejs/test-worker-dep-cjs' as well (
visualizer).

I expect the default export part to be a separate segment.

It looks like some mapping for StringLiteral isn't emitted when StringLiteral::print is replaced with directly calling print_quoted_utf16 in #8839.

Ah, I see. I probably have to call p.add_source_mapping(self.span).

Fixed in #9064.
