`ViewportBuilder` expects position to be in logical coordinates, but it was being passed in pixels. To fix, scale by the active monitor size and `egui_zoom_factor`.

More testing is complete. This works on other zoom factors and monitor scales too! |

Thanks for the additional testing! |

Compare this gif to the one on the issue report.  ### Investigation notes - [`WindowSettings.inner_position_pixels` and `WindowSettings.outer_position_pixels`](https://github.com/emilk/egui/blob/master/crates/egui-winit/src/window_settings.rs#L8-L12) are stored in physical/pixel coordinates. - `ViewportBuilder::with_position` expects to be passed a position in _logical_ coordinates. - Prior to this PR, the position was being passed from `WindowSettings` to `with_position` [without any scaling](https://github.com/emilk/egui/blob/master/crates/egui-winit/src/window_settings.rs#L61-L68). This was the root cause of the issue. - The fix is to first convert the position to logical coordinates, respecting the scaling factor of the active monitor. This requires us to first determine the active monitor, so I factored out some of the logic in [`clamp_pos_to_monitor`](https://github.com/emilk/egui/blob/master/crates/egui-winit/src/window_settings.rs#L130) to find the active monitor.
