    Original change's description:
    > [wasm] Lazy update instances on a shared Memory.Grow
    > 
    >  - Introduce a GROW_SHARED_MEMORY interrupt, and handler
    >  - Memory objects for isolates are updated on a stack check, add
    >    tracking for isolates that hit the stack check
    >  - When enough memory is not reserved ahead of time, fail to grow
    >  - Add tracking for externalized buffers in the MemoryTracker so
    >    that the MemoryTracker will know when backing_stores can be freed.
    >  - For shared buffer, do not always allocate a new buffer when
    >    growing an externalized buffer
