Subject: [PATCH] deps: V8: cherry-pick 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().
