turbopack support

[RJWadley]

adds turbopack support to @vanilla-extract/next-plugin

turbopack doesn't have any sort of external API yet, so in order to evaluate the contents of our *.css.ts files we need to compile it separately using @vanilla-extract/compiler. To avoid import resolution mismatches, we defer module resolution to turbopack via its webpack-compatible api.

we import css using data URI sources

next/font doesn't work out of the box because turbopack has custom logic for it, so we transform any modules that use it in a css context to contain static references to the generated font family, style, and weight.

we also have to stub several next-only modules to prevent them from accidentally running in rare cases during build, which would obviously fail.

fixes #1367

@mattcompiles @askoufis Can anyone take a look at this? This is a pretty important feature for next.js users. Or should we consider the project dead? Last PR was merged in early August, basically no activity from maintainers since then. Not meaning to bash anyone, I know it's thankless work maintaining open source software, but it would be nice to know what we can expect from this project. Thanks in advance!

A PR was merged in September. Reviews take time and ongoing work is often slow. All current maintainers have professional commitments and/or families.

I try to look at PRs when I have spare time/motivation, which is often quite sporadic. I'm currently on holiday, but I intend to make some headway on open PRs and repo maintenance in when I get back in early November.

Thanks for your reply! I was a bit too dramatic, sorry about that. Enjoy your holiday, and let me know if I can help with anything to get this PR going.
