Description
### Describe the bug
If you try to bind an enum to a CommandParameter in UWP, then UWP tends to pass them around the system as the raw type of the enum as opposed to the .net type.
This means that when you bind to it and it fires the CanExecute(object?), that it fails because the type does not match (uint != SortOrder)
### Regression
_No response_
### Steps to reproduce
I've provided a bare-bones reproduction here:
https://github.com/[AtomicBlom/EnumRelayCommandTest](https://github.com/AtomicBlom/EnumRelayCommandTest)
But if you create a blank app, and add a ViewModel based on ObservableObject, something like this:
```csharp
public partial class MainPageViewModel : ObservableObject
{
[RelayCommand]
private void OnSetSortOrder(SortOrder order)
{
Debug.WriteLine($"Sort order set to {order}");
}
}
public enum SortOrder : uint
{
Ascending,
Descending
}
```
Then attempt to bind to it.
```xaml
Ascending
```
You'll find that it fails
### Expected behavior
You should be able to pass an enum as a CommandParameter
