Refactor Context Menus and make them use XAML & stylesheets (#4768)

* XAML verb menu

* fix ghost FOV

* spacing

* rename missed "ContextMenu"->"EntityMenu" instances

* move visibility checks to verb system

* update comment

* Remove CanSeeContainerCheck

* use ScrollContainer measure option

* MaxWidth / texxt line wrapping

* verb category default

Now when you click on a verb category, it should default to running the first member of that category.

This makes it much more convenient to eject/insert when there is only a single option

* only apply style to first verb category entry

* Use new visibility flags

* FoV -> Fov

* Revert "only apply style to first verb category entry"

This reverts commit 9a6a17dba600e3ae0421caed59fcab145c260c99.

* make all entity menu visibility checks clientside

* Fix empty unbuckle category

* fix merge
