CheckBox focus rectangle has no padding

[JohnTasler]

Describe the bug

The focus rectangle shown around a CheckBox has no padding between it and the content of the CheckBox. The root of the issue is that the ControlTemplate for the CheckBox does not utilize the control's Padding property.

To Reproduce

Use the TAB key to set focus to a CheckBox. Observe that, regardless of the CheckBox.Padding, the focus rectangle has no padding between it and the content of the CheckBox.

Expected behavior

The CheckBox.Padding should be applied to the control's ControlTemplate, which fixes the focus rectangle issue.
