This replaces `ver_rct_non_semantics_simple_cached()` with an API that offloads the responsibility of tracking input verification successes to the caller. The main caller of this function in the codebase, `cryptonote::Blockchain()` instead keeps track of the verification results for transaction in the mempool by storing a "verification ID" in the mempool metadata table (with `txpool_tx_meta_t`). This has several benefits, including: * When the mempool is large (>8192 txs), we no longer experience cache misses and unnecessarily re-verify ring signatures. This greatly improves block propagation time for FCMP++ blocks under load * For the same reason, reorg handling can be sped up by storing verification IDs of transactions popped from the chain * Speeds up re-validating every mempool transaction on fork change (monerod revalidates the whole tx-pool on HFs monero-project#10142) * Caches results for every single type of Monero transaction, not just latest RCT type * Cache persists over a node restart * Uses 512KiB less RAM (8192*2*32B) * No additional storage or DB migration required since `txpool_tx_meta_t` already had padding allocated * Moves more verification logic out of `cryptonote::Blockchain` Furthermore, this opens the door to future multi-threaded block verification speed-ups. Right now, transactions' input proof verification is limited to one transaction at a time. However, one can imagine a scenario with verification IDs where input proofs are optimistically multi-threaded in advance of block processing. Then, even though ring member fetching and verification is single-threaded inside of `cryptonote::Blockchain::check_tx_inputs()`, the single thread can skip the CPU-intensive cryptographic code if the verification ID allows it. Also changes the default log category in `tx_verification_utils.cpp` from "blockchain" to "verify".

Otherwise we can end up double counting txs towards the weight, which can over-state the pool weight. E.g. relay tx to node in stem phase, add its weight to pool weight, then receive tx from another node, then bump the pool weight again. That double counts the tx towards the pool weight. If the weight exceeds the max, the node will "prune" txs from the pool. Thus, over-counting is probably a cause of, but perhaps not the only cause of: seraphis-migration#148
Curve Trees: handle get_max_concurrency() == 0
tx pool: only increment m_txpool_weight for newly added pool txs
Also add payment ID paramater to `on_money_received()` wallet callback.
