init_

Initializes Libadwaita.

This function can be used instead of funcGtk.init as it initializes GTK implicitly.

There's no need to call this function if you're using classApplication.

If Libadwaita has already been initialized, the function will simply return.

This makes sure translations, types, themes, and icons for the Adwaita library are set up properly.
