fix node externals resolving

[sokra]

What?

Various fixes in handling of externals in node.js

• add extensions to builtin externals to allow node.js ESM to work
• improve the auto-externals logic to detect more edge cases
• prepare for esmExternals support, but that's blocked by client manifest missing the async flag
• currently only esmExternals: false is supported

Why?

Turbopack Changes

• fix(turbopack): postcss should be applied to @imported CSS files turbo#6531
• fix node.js externals turbo#6530
