Move tracing next-server to next build (#30190)
As discussed this moves tracing `next-server` into `next build` since the pre-trace at publish time isn't able to reliably give us file locations since `node_module` file locations can vary based on installation. This also adds caching the trace so that we only need to retrace `next-server` when a lockfile changes.
A follow-up PR will add documentation for these traces explaining how they can be leveraged.
