Drop import-meta-resolve & es-main

[nobkd]

This is currently WIP. Tests probably fail on jest too.

This will change the behavior of importing esbuild and lightningcss and probably other imported modules slightly, because they now have to be installed relative to the nuekit installation, and not in the nue project. If someone wants to have modules only for a specific project now, they'll also need the nuekit installation in the project itself. This is just a hunch, I'd have to check that more.

TODO:

• drop es-main
• drop import-meta-resolve
• ignore jest peer dependency conflict on npm
• check if resolve behavior is really different now for project js imports

Makes sense. I think we need to have the local installation option available anyway. Not everyone likes the global option.
