Subject: Make all SignatureChecker explicit about missing data

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
