[roll] Roll fuchsia [kernel][vm] Split out discardable tracking

Move out all the state required for discardable VMO tracking from
VmCowPages into a new DiscardableVmoTracker class. If a VMO is
discardable, its VmCowPages retains a unique_ptr to a
DiscardableVmoTracker object, otherwise it is set to nullptr. This
avoids unnecessarily tracking unused discardable state logic for
non-discardable VMOs.
