Store JavaScript bytecode side data in the WebContent HTTP memory cache and replay it when serving cached responses. Also update an already-complete memory-cache entry when asynchronous bytecode cache generation finishes, so the first source-only response does not keep shadowing the disk-cache sidecar during same-process navigations. Keep the HTTP memory-cache backfill keyed with the request headers that populated the memory-cache entry, so Vary responses still receive their generated bytecode sidecar. Add LibHTTP coverage for round-tripping bytecode side data through a memory-cache entry, attaching it after the response body has already been cached, and matching Vary headers during updates. Add LibWeb coverage for preserving the memory-cache request headers when cloning responses.
