config_tools: add ivshmem providers

Browse Source 
A shared memory region can be provided either by the hypervisor or by the
device model. Before recent schema changes this is telled by the "hv:/" or
"dm:/" prefix.

This patch adds another node under an IVSHMEM region to represent the
provider, following the practice that information in the old-school
encodings is split and put as separate XML nodes.
