Introduce dedupused/dedupsaved pool properties
Currently there is only a dedup ratio reported via pool properties.
If dedup is enabled only for some datasets, it is impossible to say
how much space the ratio actually covers.  Fix this by introducing
dedupused/dedupsaved pool properties, similar to earlier added
block cloning ones.  Combined with work to expose allocation classes
stats, it should give user-space enough visibility to correlate
`zpool list` and `zfs list` space numbers.
