[WL21389] Fixes issue with the ShapeData vert buffer offset (details below).

Browse source 
When computing the buffer view offset for ShapeData the vertex vector
size should be scaled by a single vec3 size as opposed to 2.

This fix is taken from PR discussion:
 https://github.com/1P-Cusack/hifi/pull/10

 Proposed by: Andrew Meadows <andrew@highfidelity.io>
