Containers: use the implicit size of the contentItem

The result of:

   Frame {
       ColumnLayout {
           RadioButton { text: "First" }
           RadioButton { text: "Second" }
           RadioButton { text: "Third" }
       }
   }

is now identical to:

   Frame {
       contentItem: ColumnLayout {
           RadioButton { text: "First" }
           RadioButton { text: "Second" }
           RadioButton { text: "Third" }
       }
   }
