deps: V8: cherry-pick 367b0c1e7a32

Original commit message:

    [runtime] Change default scope info for SyntheticFunctionContexts

    This changes the default scope info for SyntheticFunctionContexts
    to the EmptyScopeInfo which does not contain an extension slot.

    The bug happened because, previously, the native context scope info
    was used as dummy.
