DRW: Pointcloud: Refactor drawing to remove instancing

This change the attribute binding scheme to something similar to the
curves objects. Attributes are now buffer textures sampled per points.

The actual geometry is now rendered using an index buffer that avoid too
many vertex shader invocation.

Drawcall is wrapped in a DRW function to reduce complexity of future
changes.
