UI: Menu items can be cut off / unreachable in small windows

[ES-Alexander]

Summary

Version: 2.3.4

Operating System: All

What is happening: Ping Viewer menus have a fixed size, and do not support scrolling when the window is smaller than the menu, which can cut off menu items. This is particularly problematic on small screens (where some menu items may be completely inaccessible), or when users want a small Ping Viewer window to sit on top of their vehicle's GCS.

How to reproduce it: Open PingViewer, open a menu, resize the application to be smaller than the menu, fail to access the now hidden items.
