Draft: Add PEP-658 support
This PR adds PEP 658: Serve Distribution Metadata in the Simple Repository API support to micropip, which means that when using Simple API to install a package, micropip will check for distribution metadata and downloads it simultaneously with the wheel to speed up dependency resolution.
I think this PR is mostly ready, but I'll split it into 2-3 PRs, and add more tests (it is kinda tricky to write a test for this), so I'm opening it as a draft.
Thanks for working on this!
Related question @ryanking13 : do we do (or plan to do) anything with the .whl.metadatafiles we create and distribute via jsdelvir? As currently they are not being served by the CDN https://github.com/jsdelivr/jsdelivr/issues/18531

Yes, that's a good point. I think we'll need to serve .metadata files using jsdelivr in the future. If I understand correctly, there has been some work in the direction of allowing the pyodide distribution to be used as a package index. (I don't know what this will eventually look like).
