Merge #10409: [tests] Add fuzz testing for BlockTransactions and BlockTransactionsRequest

Browse Source 
fd3a2f3 [tests] Add fuzz testing for BlockTransactions and BlockTransactionsRequest (practicalswift)

Pull request description:

  The `BlockTransactions` deserialization code is reachable with tainted data via `ProcessMessage(…, "BLOCKTXN", vRecv [tainted], …)`.

  The same thing applies to `BlockTransactionsRequest` which is reachable via `"GETBLOCKTXN"`.
