v2.1: Fix flaky test_transaction_result_does_not_affect_bankhash (backport of #3916)

[mergify]

Problem

• test_transaction_result_does_not_affect_bankhash is flaky due to random keypairs/pubkeys
• The flakiness comes down to rent collection (rather updating rent epoch)
• In successful transactions, we collect rent during transaction processing for writable accounts
  • in this case, that will be the mint_keypair's pubkey
• In bank.freeze, we collect rent on partition(s)
  • in this case, that will be the mint_keypair IF the randomly generated key is in the partition
• IF the mint pubkey falls in the bank's rent collection partitions, the bankhash is unaffected since the rent is collected in both cases

Summary of Changes

• Use deterministic keys in the test, and in other tests

I was working on other stuff today so rushed through the merge conflict; should be corrected now + paper-trail explaining why it previously failed

[steviez]

This is the assertion we need to do as noted by what we have in master:

agave/ledger/src/blockstore_processor.rs

Line 3660 in 1e721f0

assert_eq!(ok_bank_details == bank_details, fee_payer_in_rent_partition);

which you can also see is what was added in the initial PR:
https://github.com/anza-xyz/agave/pull/3916/files#diff-281d947e593a76f3c3380804162dc8cf426fcc33e0ae1192589c8193221cd1e2R3626

So the merge conflict needed to bring this check from c5473e4, but keep the rest from v2.1 head

What's the justification/catalyst to backport this?

What's the justification/catalyst to backport this?

Came up in backport meeting. Motivations is just reducing the amount of times we have to hit the retry button in CI when backporting to 2.1
