Fix for D3D12 re-used bindgroup bug.

If a bindgroup was re-used in multiple command buffers in a single call
to queue.Submit(), it was skipping the creation of the corresponding
descriptor heap for that bind group in the second command buffer.

The fix is to use the command buffer's index into the submit command as
part of the key for the bind group's descriptor heap.
