Invoke cost tracker from its bank (backport #20627) (#20800)

* - make cost_tracker a member of bank, remove shared instance from TPU; (#20627)

- decouple cost_model from cost_tracker; allowing one cost_model
  instance being shared within a validator;
- update cost_model api to calculate_cost(&self...)->transaction_cost

(cherry picked from commit 7496b5784b)
