Instead, smuggle it in as a `void*` private data and let Javascript aware code cast out that pointer to a VM&. In order to make this split, rename JS::Cell to JS::CellImpl. Once we have a LibGC, this will become GC::Cell. CellImpl then has no specific knowledge of the VM& and Realm&. That knowledge is instead put into JS::Cell, which inherits from CellImpl. JS::Cell is responsible for JavaScript's realm initialization, as well as converting of the void* private data to what it knows should be the VM&.
