Ava Chow 00ad998d95 Merge bitcoin/bitcoin#33252: p2p: add DifferenceFormatter fuzz target and invariant check 
65a10fc3c5 p2p: add assertion for BlockTransactionsRequest indexes (frankomosh)
58be359f6b fuzz: add a target for DifferenceFormatter Class (frankomosh)

Pull request description:

  Adds a fuzz test for the [`DifferenceFormatter`](e3f416dbf7/src/blockencodings.h (L22-L42)) (used in [`BlockTransactionsRequest`](https://github.com/bitcoin/bitcoin/blob/master/src/blockencodings.h#L44-L54), [BIP 152](https://github.com/bitcoin/bips/blob/master/bip-0152.mediawiki)). The DifferenceFormatter class implements differential encoding for compact block transactions (BIP 152). This PR ensures that its strictly-monotonic property is maintained. It complements the tests in [`blocktransactionsrequest_deserialize`](9703b7e6d5/src/test/fuzz/deserialize.cpp (L314)).

  Additionally, there's an added invariant check after GETBLOCKTXN deserialization in `net_processing.cpp`.
