deps: V8: cherry-pick 3dd9576ce336

Original commit message: [inspector] Support Symbols in EntryPreview The Symbols-as-WeakMap-keys proposal allows non-Symbol.for Symbol values in weak collections, which means it can show in EntryPreviews. Also apparently Symbols in regular Maps and Sets were also unsupported.
