Remove the implicit MissingDataBehavior::ASSERT_FAIL in the *TransationSignatureChecker constructors, and instead specify it explicit in all call sites: * Test code uses ASSERT_FAIL * Validation uses ASSERT_FAIL (through CachingTransactionSignatureChecker) (including signet) * libconsensus uses FAIL, matching the existing behavior of the non-amount API (and the extended required data for taproot validation is not available yet) * Signing code uses FAIL
