An array of resources in Vulkan only consumes one binding

Fixes #84

- When computing resource usage for an array type, don't multiply the resource usage of the element type by the element count foor descriptor-table-slot resources.

- When reporting the "stride" of an array type through reflection, report the stride for descriptor table slots as zero, always.
