This PR adds the helper module egui::gui_zoom which has keyboard shortcuts and GUI elements for zooming a whole GUI app (by modifying Context::pixels_per_point), similar to how you can zoom a web page (or an egui app in a web page).

The demo app now listens for Cmd+Plus and Cmd+Minus to zoom the GUI.

Closes #1721
