WinUI Fluent/Windows 11 eval

[Redth]

Just as in #3444 we need to remove the old control templates we have overridden previously and revert to the defaults implicitly. We are switching to use resource dictionary to set styles for the colors as needed.

These styles currently exist in: src\Core\src\Platform\Windows\Styles.

The remaining Controls are:

• Activity Indicator - Use default control templates for WinUI3 #5143
• Auto Suggest Box - Use default control templates for WinUI3 #5144
• CheckBox - Use default control templates for WinUI3 #5145
• ComboBox - Use default control templates for WinUI3 #5146
• Slider - Use default control templates for WinUI3 #5147
• Stepper - Use default control templates for WinUI3 #5148
• NavigationRoot - Use default control templates for WinUI3 #5149
• WinUI Resources XAML - Evaluate/Remove unneeded styles #5150
• RadioButton - Use default control templates for WinUI3  #5502

An example is here: #3444

NavigationRoot should be using default templates

I'm not using any generated style templates anywhere for WinUI navigation parts

Look at that, progress already!

I discovered that RadioButton is missing from the list, so opened #5502. Hope I applied the right labels.

Closing, since all sub-issues are fixed.
