`Store::new` is an infallible constructor, so there is not a direct way to make it return an error on OOM. Additionally, it is one of the most-used functions in the Wasmtime embedder API, so changing its signature to return a `Result` is a non-starter -- it would cause way too much pain. So instead we define `Store::try_new` which returns a `Result` and make `Store::new` call and unwrap that new constructor. Part of bytecodealliance#12069
