Merge branch 'ui_rework_4_0' into CURA-5876-Configuration_dropdown

Conflicts:
	plugins/PrepareStage/PrepareMenu.qml: Git was wrong, this was not really a conflict.
	resources/qml/ActionButton.qml: With iconSource being modified on ui_rework_4_0 and me modifying the icon to be able to display it on the left hand side.
	resources/qml/ActionPanel/OutputProcessWidget.qml: Git was wrong, not really a conflict.
	resources/qml/ActionPanel/SliceProcessWidget.qml: Git was wrong, not really a conflict.
	resources/qml/ExpandableComponent.qml: Both ui_rework_4_0 and me implemented a border around popups.
	resources/qml/MainWindow/MainWindowHeader.qml: Git was wrong, not really a conflict.
	resources/themes/cura-light/theme.json: Theme item was added in a place where I added whitespace.
