This isn't needed, there's no Grid, so I removed it as well.

I also added this so ContentTemplate can be used.

This caused the toggle button to be off-center, there's no need for this, so just remove it.

So we can override the style of the toggle button without having to redeclare the entire template.
Update SplitButton.xaml

This had to be changed to PreviewMouseLeftButtonUp for two reasons.
- If the Click event is used, there's hardly any visible Pressed state as it instantly presses.
- The SplitButton's context menu would immediately open on mouse down, this isn't the same in WinUI, where a mouse up is required.

What is the current behavior?
Currently, a SplitButton has a mouseover/pressed color for the entire element. This isn't what WinUI does, it only changes this for the part hovered over (i.e., content and the toggle button).
New:
(only toggle has mouseover brush).
(only content has mouseover brush).
Old:
(entire button has mouseover brush).
