Per-entrypoint cache config; cross-version cache enabled

Minor Changes

• #14474 aa5d580 Thanks @WillTaylorDev! - Add cache options for WorkerEntrypoint exports

  You can now set cache options on WorkerEntrypoint exports and configure cross-version cache behavior globally:

  // wrangler.json
  {
    "cache": { "enabled": true, "cross_version_cache": true },
    "exports": {
      "default": {
        "type": "worker",
        "cache": { "enabled": false }
      },
      "Admin": {
        "type": "worker",
        "cache": { "enabled": true }
      }
    }
  }

  Wrangler sends the exports config to the deploy and version upload APIs alongside the global cache.enabled and cache.cross_version_cache settings. The platform resolves those global settings plus cache overrides on exports and validates which entrypoint names are cacheable.
