Create optimize materials for hand joint mesh visualization

[Troy-Ferrell]

Overview

This change creates two new materials to be used directly with the default hand joint mesh visualization.

One material for the hand joint cubes. This new material is opaque instead of transparent allowing for true dynamic batching of all joints into a combined draw call.

One material for the hand joint index tip spheres. This material turns off hover light and other unnecessary items and turns on GPU instancing so both index tips are drawn in one call.
