MarcoFalke 8ca90f3f99 Merge #15891: test: Require standard txs in regtest by default
fa89badf887dcc01e5bdece248b5e7d234fee227 test: Require standard txs in regtest (MarcoFalke)
fa9b4191609c3ef75e69d391eb91e4d5c1e0bcf5 test: Add test that mainnet requires standard txs (MarcoFalke)
fa613ca0a8f99c4771859de9e571878530d3ecb5 chainparams: Remove unused fMineBlocksOnDemand (MarcoFalke)

Pull request description:

  I don't see a reason why regtest should allow non-standard txs, as it makes testing mainnet behaviour such as #15846 unnecessarily hard and unintuitive.

  Of course, testnet policy remains unchanged to allow propagation of non-standard txs.
