Initialize the stream components common to all GPU skin vertex factory types

Parameters

VertexFactoryData	- context for setting the vertex factory stream components. commited later
VertexBuffers	- vertex buffers which contains the data and also stride info
bUseInstancedVertexWeights	- use instanced influence weights instead of default weights
