      Revert of [wasm] WebAssembly.Memory object can be referenced by multiple Instance objects. (patchset #10 id:180001 of https://codereview.chromium.org/2471883003/ )

Reason for revert:
Breaks gc stress:
https://build.chromium.org/p/client.v8/builders/V8%20Linux%20-%20gc%20stress/builds/7114

Original issue's description:
> [wasm] WebAssembly.Memory object can be referenced by multiple Instance objects.
>
> Add support for WebAssembly.Memory objects to be simultaneously referenced by multiple Instance objects. GrowingMemory should maintain a consistent view of memory across instances.
>  - Store a link to instances that share WebAssembly.Memory in the WasmMemoryObject, updated on instantiate.
>  - Implement WasmInstanceWrapper as a wrapper around the instance object to keep track of previous/next instances, instance object is stored as a WeakCell that can be garbage collected.
>  - MemoryInstanceFinalizer maintains a valid list of instances when an instance is garbage collected.
>  - Refactor GrowInstanceMemory to GrowMemoryBuffer that allocates a new buffer, and UncheckedUpdateInstanceMemory that updates memory references for an instance.
