d02dfc6e - feat(turbopack): add support for esm externals in app dir (#64918)

feat(turbopack): add support for esm externals in app dir (#64918) ### What? Writes the async flag to the client reference manifest to support ESM externals in app dir. The `app-ssr` context can't have esm externals as that might cause a module to be async in ssr but not on the client. Closes PACK-2967 Fixes #64525
