devices: gpu: modify resource v2

Rebase of zero-copy virtio-gpu flow:

    * Removes guest_memory_type/guest_caching_type in favor of a bitmask
    * Removes ALLOCATION_METADATA, since ideally we'd just read from
      guest memory to get guest responses
    * Renames HOST_COHERENT to HOST_VISIBLE
    * Adds a few more feature flags
