Use cluster confirmations in rpc and pubsub (#9138)

Browse Source 
* Add runtime methods to simply get status and slot

* Add helper function to get slot confirmation_count from BlockCommitmentCache

* Return cluster confirmations in getSignatureStatus

* Remove use of invalid get_signature_confirmation_status

* Remove unused methods

* Update pubsub to use cluster confirmations

* Fix test_check_signature_subscribe failure

* Refactor confirmations to read commitment cache only once

* Review comments

* Use bank, root from BlockCommitmentCache

* Update docs

* Add metric for block-commitment aggregations
