Pass the HwndSource parameters directly

lindexi · lindexi · commit 3d3c03e1b72b · 2025-09-17T17:58:47.000+08:00
The RegisterHwndForInput only be called by `HwndStylusInputProvider..ctor`. And the `HwndStylusInputProvider..ctor` will pass the `HwndSource source` to RegisterHwndForInput method. So that it unnecessary to use the PresentationSource in RegisterHwndForInput.
