[gnome-builder] libide: add ide_language_get_source_language()

    libide: add ide_language_get_source_language()
    
    Add helper to get the GtkSourceLanguage for a given IdeLanguage. If
    GtkSourceLanguage were subclassable, we'd probably just subclass
    GtkSourceLanguage instead. But composition works fine too.
