MacOS: Set mouse delta to move and drag event

[chutneyio]

This PR fixes the issue where pen drag to pan does not work in some apps which requires mouse delta.
Fixes #3048

Test if this works on both absolute and relative output modes. This looks redundant to what this does:

OpenTabletDriver/OpenTabletDriver.Desktop/Interop/Input/Relative/MacOSRelativePointer.cs

Lines 28 to 33 in 5218f43

	protected override void SetPendingPosition(IntPtr mouseEvent, float x, float y)
	{
	CGEventSetLocation(mouseEvent, GetCursorPosition() + new CGPoint(x, y));
	CGEventSetDoubleValueField(mouseEvent, CGEventField.mouseEventDeltaX, x);
	CGEventSetDoubleValueField(mouseEvent, CGEventField.mouseEventDeltaY, y);
	}

And will likely break relative output mode. Probably only change OpenTabletDriver.Desktop/Interop/Input/Absolute/MacOSAbsolutePointer.cs

@X9VoiD Yeah this issue only happens in absolute mode. I moved the code to MacOSAbsolutePointer.cs
