Allow specifying which file descriptor is used in console.{log,err} from the CLI

[Niikelion]

Operating system: windows + wsl2-ubuntu, windows Processor architecture: x86_64 Rust version: rustup 1.27.0 Javy version: javy 1.4.0

Problem

After compiling console.log("test") into .wasm file and executing it with wasmtime I get output on stderr instead of stdout. I verified that its not an wasmtime problem by compiling and running simple c program with printf("test\n"). Testing was done in windows and wsl2 with ubuntu on windows and in happens in both cases.
