[unity] Added ontline-only single pass shaders to LWRP and URP packages. This allows for separate outline child GameObjects that reference the existing Mesh of their parent, and re-draw the mesh using this outline shader.

Browse Source 
The component to ease replacing materials of the parent will be added in separate upcoming commit.
