Unfortunately it's not as simple as passing the indirect draw count buffer to ExecuteIndirect. The compute job that populate the execute buffer also needs to know the number of entries that need to be patched. Instead of transitioning the indirect count buffer from GENERIC_READ to INDIRECT_ARGUMENT we just keep at as a read-only resource and copy the draw_count value to the exec buffer in the compute job.
