    libide/foundry: add translation API to IdeConfig
    
    We really want this at the config level than just on a runtime because
    it allows more control over complex resolution. For example, Flatpak
    manifests will need to look in SDK extensions, SDKs, Debug runtimes,
    the platform runtime, and additionally the staging directory while building
    the application.
    
    This is a backport for GNOME 43 and therefore API stays private.
