CogCommonUI: Add a new plugin to fix CommonUI blocking cog shortcuts (F1, F2, ...)

Reference this plugin where other cog modules are added.
This plugin uses a CommonUI ActionRouter to let Cog receives the shortcuts it needs.
If you already have an Action Router, you can call FCogImguiInputHelper::IsTopPriorityKey to know if the key event to should handled or not.
