The flag has been enabled by default for two version now, so it is time
to remove it.

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.

Currently atomic operations are only allowed on shared WebAssembly.memory.
An attempt to use atomic operations otherwise is a validation failure, there
is an ongoing attempt to allow Wasm atomic operations on any memory object.
https://github.com/WebAssembly/threads/issues/144
This CL adds experimental support for allowing atomic operations on all
memory objects behind the --wasm-atomics-on-non-shared-memory flag. Note
that Wait/Notify may not work as expected as they have additional checks
to ensure that the memory is a SAB.
