GPU_pbvh_buffers: Use triangles to render multires.

A question here might be: why?

The answer is that GPUs will convert this to triangles so we are wasting
memory during conversion of the element buffer to a triangle buffer
anyway.

The second reason is that some modern GPUs are slower rendering GL_QUADS

The third reason is that due to element caching, this should not in
theory be slower (cached elements do not get recalculated on the GPU).
