Fix dragging of `custom_window_frame` on Windows (#4592) 

Fix: example `custom_window_frame`

Sending `ViewportCommand::StartDrag` when the secondary button is
clicked in Windows will disable drag, and drag will not be possible with
the primary button afterwards.

So in the example `custom_window_frame`, modified to use
`dragged_by(PointerButton::Primary)` instead of
`is_pointer_button_down_on()`.
