vhost-iova-tree: Implement an IOVA-only tree
Creates and supports an IOVA-only tree to support a SVQ IOVA->HVA and GPA->IOVA tree for host-only and guest-backed memory, respectively, in the next patch. The IOVA allocator still allocates an IOVA range but now adds this range to the IOVA-only tree as well as to the full IOVA->HVA tree. In the next patch, the full IOVA->HVA tree will be split into a partial SVQ IOVA->HVA tree and a GPA->IOVA tree. The motivation behind having an IOVA-only tree was to have a single tree that would keep track of all allocated IOVA ranges between the partial SVQ IOVA->HVA and GPA->IOVA trees.
