Add a "Debug" Rendering pipeline that draws meshes in wireframe

There should be a `PipelineFlags` options for "Debug" which will build a render pipeline enabling you to draw wireframe meshes

This is a really important feature that I want to have because how we implement this should be same was as we would a new shader effect, like an outline shader. It's important that the design is scalable to have as many materials/visual effects that we want here and that it is easily extensible to the end user (a graphics programmer making a new effect)
