internal/prompt: allow compilation in js/wasm environment
The wallet loader has a dependency to the internal/prompt package for prompting the user for certain inputs (e.g. wallet password or new seed). This makes it impossible for projects that use the wallet as a dependency and always provide those inputs as parameters to compile for JavaScript/WebAssembly targets because the prompt code uses some terminal functionality that is not available in JS syscalls. By providing a JS specific implementation that just returns an error we can compile the dependent projects. Adding acutal support for prompting the user in the browser is currently not planned as that can easily be circumvented by providing all inputs as parameters.
