Add "list" and "any_external" options to shade_display_override command

Those options allow to list the available displays (and see which one had the shade), and set the shade window on the first non-default display without caring about display ids.

+ Small refactor to use dagger in ShadePrimaryDisplayCommand and decouple it from ShadeDisplaysRepository

To use them "adb shell cmd statusbar shade_display_override list" or "any_external"
