    Clickable Interactive control sample for custom titlebar (microsoft#1360)

    With 1.4 changes, WinUI 3 custom titlebar now uses appwindow titlebar + nonclientinputpointersource apis under the hood. This opens up new possibilities like allowing clickable interactive controls like textbox, button in the titlebar area, surrounded by draggable region on both left and the right sides.

    This code adds a sample to titlebar page which shows users how to create interactive controls in winui 3 titlebar. It also demonstrates the power of mixing and matching high level winui 3 custom titlebar apis and low level nonclient apis.
