This adds tracing entrypoints directly after they have have been transpiled to allow us to trace before the webpack runtime has been added to the modules. This should allow for more accurate tracing of entrypoints and allow the trace step to be cached. ## Bug - [x] Related issues linked using `fixes #number` - [x] Integration tests added x-ref: https://github.com/vercel/next.js/issues/24700 x-ref: https://github.com/vercel/next.js/issues/26200 x-ref: https://github.com/vercel/next.js/issues/23894 x-ref: https://github.com/vercel/next.js/issues/25431
