gallium/docs: Make it clear that minIndex, maxIndex is exclusively a index buffer characteristic.

``indexBias`` is a value which is added to every index read from the index
buffer before fetching vertex attributes.
+``minIndex`` and ``maxIndex`` describe minimum and maximum index contained in

If a given vertex element has ``instance_divisor`` set to 0, it is said
it contains per-vertex data and effective vertex attribute address needs
to be recalculated for every index.
