refactor: enable source maps for running executable

[peter-jerry-ye]

• Related issues: None
• PR kind: optimization

Summary

Always enable sourcemaps even for running moon run --target js.

The rational is that we are adding mangling for all the symbols. Not using sourcemap would make the backtrace almost useless.

Metadata

• Tests added/updated for bug fixes or new features
• Compatible with Windows/Linux/macOS
