Back navigation button styles seem to be reversed

[lesterbotello]

Describe the bug

Using the styles NavigationBackButtonNormalStyle and NavigationBackButtonSmallStyle in a button results in appearances that appear to be the opposite of what they're intended to do. Namely, the NavigationBackButtonNormalStyle results in a button that actually looks smaller than the NavigationBackButtonSmallStyle button (refer to the screenshot and the attached sample app for visual proof).

Steps to reproduce the bug

1. Create a new Blank desktop app (Win UI)
2. Add the following to the main page:

	<StackPanel HorizontalAlignment="Center"
				VerticalAlignment="Center">
		<TextBlock Text="Normal Button (NavigationBackButtonNormalStyle):" />
		<Button Style="{StaticResource NavigationBackButtonNormalStyle}" />
		<TextBlock Text="Small Button (NavigationBackButtonSmallStyle):" />
		<Button Style="{StaticResource NavigationBackButtonSmallStyle}" />
	</StackPanel>

3. Run the app and observe the two buttons

Expected behavior

Buttons styled with NavigationBackButtonSmallStyle are actually smaller than the ones styled with NavigationBackButtonNormalStyle
