Take two for r8466:

Replace the old attribute binding and index interface with one where we include the binding as part of the attribute array. Also removed the fixed attribute indices for constant color and coverage attributes, and replaced with dynamic ones based on current attribute set. Removed binding of color and coverage attributes unless they're actually set.
