[roll] Roll fuchsia [kernel][vm] Slot based compression storage

Adds a slot based compressed storage system that can store up to 64
items on a single page. Unlike the VmTriPageStorage system, the slot
storage cannot store all the allocation metadata in the vm_page_t and
utilizes a slab allocator.

Compared to the VmTriPageStorage, which stores at best 3 items per
page, this storage system can store up to 64 items and in real
workloads can reduce the storage overhead (percentage of the allocated
storage not used for storing actual data) from 24% -> 5%.
