Deepti Gandluri 895c52ddcb [wasm] Adjust atomics wait/notify semantics
Adjust atomics.wait, atomics.notify semantics for when they are used
with non-shared Wasm memory to mirror the spec change introduced
in: https://github.com/WebAssembly/threads/pull/147. This does not
need to be gated by the flag here, as this will only decode if
the flag is enabled.
