How to get memory in an import function in 3.0 for multiple instances?

[Berrysoft]

According to #3113, the only case to get the memory field is after the instance being created. However, I want to manage multiple instances with one engine and one store. All instances need the same import functions. Does that mean I need to create the same functions multiple times? Are there any overhead?

I've been scratching my head over this as well, mostly since I want access to memory to read strings from WasmPtr. But to get memory you need to get an instance first, which you get after the fact of creating it with imports.

As currently implemented, you can only have one wasmer::Store per instance. @ptitSeb is working on making the engine shareable between instances as part of #3378.
