2777300c68 fuzz: Implement connect_block harness (Robin David)
40add915be test: Add reset to CuckooCache (Eugene Siegel)
Pull request description:
Adds a fuzz target that directly calls `ConnectBlock` with `fJustCheck` set to true, so it hits block/transaction validation without writing undo data or updating the chainstate.
This PR is essentially https://github.com/bitcoin/bitcoin/pull/34651 with some minor tweaks and style cleanups. Additional validation harnesses (e.g. https://github.com/bitcoin/bitcoin/pull/34895) could build on this test's setup.
