dart2wasm imports strings as globals for which JavaScript engines would provide the respective values. The standalone target needs to support all WebAssembly runtimes, so it can't rely on this mechanism. Instead, this imports functions to convert a WebAssembly arrays of char codes or ASCII bytes into a string. For now, these functions have to return JS strings since the rest of the SDK relies on that. In the future, embedders would be able to return any string implementation as an externref. Because calling host functions is invalid in constant contexts, string constants can't be regular globals. For now, this uses the default non-eager constant implementation with one initialization function per string constant. Eventually, we should probably initialize these strings in a WASM start function instead.
