Releasing pointer capture while out of the window cause an error to be logged on WPF

[dr1rrb]

Current behavior

When we release a pointer that has been captured out of the windows bounds on WPF cause this

uno/src/Uno.UI/UI/Xaml/Internal/InputManager.Pointers.Managed.cs

Line 128 in c72870f

if (this.Log().IsEnabled(LogLevel.Error))

This seems to be because when we invoke ReleaseCapture, WPF send us synchronously a pointer leave which cause to have a second pointer event (leave) being raised while still processing the release.

Expected behavior

No errors
