hw/cxl: Add get scan media capabilities cmd support
Use simple heuristics to determine the cost of scanning any given
chunk, assuming cost is equal across the whole device, without
differentiating between volatile or persistent partitions. This
is aligned to the fact that these constraints are not enforced
in respective poison query commands.
