vkd3d: Lay out virtual descriptor heap buffer and image bindings consecutively instead of interleaving them.

Browse Source 
Slightly simplifies descriptor write addressing, and makes layouts
essentially the same as array layouts, differing only in the binding
details, and therefore easier to understand. This also simplifies the
addition of storage buffer bindings, which can all be added onto the end.
