Merge bitcoin#29547: kernel: chainparams updates for 27.x

d9f30b0 kernel: chainparams updates for 27.x (fanquake) 1611aa1 kernel: update chainTxData for 27.x (fanquake) af78d31 kernel: update nMinimumChainWork & defaultAssumeValid for 27.x (fanquake) Pull request description: Update chainparams pre `27.x` branch off. Note: Remember that some variance is expected in the m_assumed_* sizes. ACKs for top commit: Sjors: ACK d9f30b0 glozow: ACK d9f30b0 (checked mainnet locally, checked testnet/signet on block explorers and sanity checked the numbers) instagibbs: ACK d9f30b0 Tree-SHA512: 6ce65b964334b9d15fff4aa1af6d26fb3ef4eab50b8237fc2cda180230ae724a99d13c9f6b3c58105548d3520c0ca0810f354736132d11793d6c91ad3eeac4c7
