rutabaga_gfx: gfxstream: Save iovecs in gfxstream

Browse source 
The virtio gpu resource used as a ring buffer for sending
CROSS_DOMAIN_CMD_GET_IMAGE_REQUIREMENTS responses back to the
guest is created with VIRTGPU_BLOB_MEM_GUEST. Because of this, it
is initially created with via a resource_create_blob() without a
ctx_id. The rutabaga backend routes resource_create_blob() requests
without a ctx_id to the default component which is Gfxstream on
Cuttlefish. The Gfxstream component needs to attach the backing
iovecs to the RutabagaResource in order for CrossDomainContext to
eventually take ownership of them.

BUG=b:189133053
TEST=launch Cuttlefish w/ cross domain
