Make ActionButton be a ToolButton
Reason for the change
Right now ActionButton has a custom style that looks very fancy, the result of extensive VDG input years ago. It's used on the login, lock, and logout screens.
Unfortunately, its fanciness makes it visually inconsistent with all other similar buttons. It also has poor compatibility with icon themes that have square icons, and causes bugs with certain graphical setups that can break it completely.
Let's be more conventional to resolve these issues. Losing the fanciness isn't too bad since at least our current Plasma ToolButton styling is pretty good.
Test plan
- Show the lock, logout and login screens
- Navigate among buttons using the keyboard
