RFR: 8292446: Make TableRateStatistics optional in CHT

Wed Aug 17 09:52:17 UTC 2022

Right now the footprint of disabling statistics for tables where they're not used is minimal as they're single instance and static. We're working on using CHT in more contexts, where it will be dynamically allocated, and then these changes will add up to something more substantial.
