Michael Anthony Knyszek 78bb91cbd3 runtime: remove npreleased in favor of boolean
This change removes npreleased from mspan since spans may now either be
scavenged or not scavenged; how many of its pages were actually scavenged
doesn't matter. It saves some space in mpsan overhead too, as the boolean
fits into what would otherwise be struct padding.

For #14045.
