Wrong Resource Usage in Fluent2 Button Styles
Description
The following line has the wrong resource. It's using a level 2 resource key ControlElevationBorderBrush but should be using the button-specific level 3 one.
https://github.com/dotnet/wpf/blob/673c35418e5416e486e6651b69b89712a36fcf5c/src/Microsoft.DotNet.Wpf/src/Themes/PresentationFramework.Fluent/Styles/Button.xaml#L58
Looks like the accent button styles are incorrect in a similar way. In fact the resource keys we should be using are commented out. I suspect elevation brush needs to be fixed overall.
Reproduction Steps
See code.
Expected behavior
We should be using the proper resource key:

Which for some reason is commented out. All these resources need to be re-actived and used in the templates. This includes the accent button ones:

Actual behavior
As described above.
