import-analysis: external ids should not be prefixed with /@id/

[Aslemammad]

Describe the bug

I've been working on vite-plugin-jspm and I was trying to control the dependencies using export maps and JSPM!
And what I wanted to achieve is that I wanted plain externalized IDs (dependency) like { id: 'react-dom', external: true }! and not something that Vite handles (with external, we get some control, but Vite still injects /@id/ to the externalized id) here.

Expected behaviour

As far as I think, we've got two expected behaviours:

• adding an option along external, that let vite know that a specific id should not be prefixed with /@id/
• Or not prefixing the ids that have external as true!

I prefer the second one though I'm not sure if that has to do with external

Example

Since es-module-shims cannot figure out what /@id/react is, we get this error:

GET http://localhost:3000/@id/react net::ERR_ABORTED 404 (Not Found)

Reproduction

Nothing to reproduce!

I think this is a duplciate of #6582. I'm working on the feature on the side, but trying to get it polished up soon.

Sure, I'm excited about it since it opens many possibilities! Thank you for the great work, Bjorn!
