HashTable: bring per-table stats tracking back to life.
Recording per-hash table stats (DUMP_HASHTABLE_STATS_PER_TABLE)
broke with the introduction of Oilpan, as the feature depended
on finalizable HashTable<>s, something Oilpan heap hash tables
are not.
If the hash table resides on the Oilpan heap, arrange for the
stats object to also reside there.
While here, also unify the handling of global HashTable stats
recording and the per-table representation.
