Fix #4070, Visualizer Edition (#4730)

* Transform the Cloning Pod visualizer into a generic enum visualizer for simple cases like it

...I find it helpful at times like these to remind myself that our true enemy is
code. Code is what makes our programs run and generally is required for all of
these machinations to function in any way at all...

* Give the kitchen/meat spike a visualizer

* GenericEnumVisualizer: Byteify enums, switch to TryGetComponent for sprite
