deps: cherry-pick dbfe4a49d8 from upstream V8

Original commit message:

    Introduce ScriptOrModule and HostDefinedOptions

    This patch introduces a new container type ScriptOrModule which
    provides the name and the host defined options of the script/module.

    This patch also introduces a new PrimitivesArray that can hold
    Primitive values, which the embedder can use to store metadata.

    The HostDefinedOptions is passed to V8 through the ScriptOrigin, and
    passed back to the embedder through HostImportModuleDynamically for
    module loading.
