[apfitzge]

Problem

• Need to ingest new tx type into banking stage

Summary of Changes

• Implement a new TransactionViewReceiveAndBuffer to allow banking stage to ingest TransactionView-based transactions
• Add argument to BankingStage::new to switch between transaction representations
• Hook up CLI for validator and relevant benchmarks
• Run all BankingStage and SchedulerController tests using both options

NOTE: this does not run the bank.check_transactions because I prioritized safety around not leaking Bytes in the container, which is much trickier if we do batching.
We should probably follow this up with a call to clean immediately after, so that we check age on transactions we actually inserted, which is likely better anyway. However, I'd like to profile with and without that change first.

removed Hold branch here. Sometimes after a leader slot, we do not have a bank ready in Consume for our next leader slot. We should still avoid the recv_timeout in that case. Also added a check that container is not empty - if container has items, then we should try to process them instead of sleeping for packets

Looks good from SVM point of view.
