Restore Editor viewport icon rendering (#879)

This introduces an EditorViewportIconDisplayInterface that will eventually be used to outright remove CIconManager, it provides a simple interface for loading 2D image assets and rendering them on-screen. It also introduces AtomBridge::PerViewportDynamicDraw for getting a dynamic draw instance on a per-viewport basis
