deps: V8: backport cd10ad7cdbe5

Original commit message: [compiler] reset script details in functions deserialized from code cache During the serialization of the code cache, V8 would wipe out the host-defined options, so after a script id deserialized from the code cache, the host-defined options need to be reset on the script using what's provided by the embedder when doing the deserializing compilation, otherwise the HostImportModuleDynamically callbacks can't get the data it needs to implement dynamic import().
