OpenTelemetry: propagate context to sandbox

[dvoytenko]

The sandboxed request processing do not share the same async context with the BaseServer and thus the context should be propagated independently.

Notably, the headers API is different in BaseServer (Record<string, string | string[]>) vs in the sandbox (Headers), so additionally, we have to use the right getter.

Seems the resolving for edge is missing @opentelemetry/api in https://github.com/vercel/next.js/blob/0cb1c404005de79b8cfbf3eac97e90616d5d4f45/packages/next-swc/crates/next-core/src/next_import_map.rs.

Will ask the Turbopack team to take a look
