Merge bitcoin/bitcoin#21862: test: Set regtest.BIP65Height = 111 to speed up tests

faf7e485e9 Set regtest.BIP65Height = 111 to speed up tests (MarcoFalke)

Pull request description:

  No need to waste time by forcing creation of more than 1000 blocks to get the benefits of being able to test BIP 65. Also, reducing the height makes it more likely that (third-party) tests are conforming to BIP 65, which is enforced on mainnet for all new blocks.
