Cardano Updates

Same builtins already added to the Data variant: expModInteger, dropList,
array ops, BLS multi-scalar-mul, insertCoin, lookupCoin, unionValue,
valueContains, valueData, unValueData, scaleValue.

- Restore .golden.txt extension (nestedGoldenVsTextPredM expects
  name + ".golden" + ext, so the file must end in .golden.txt)
- Update CostModel/Params/CostModelParams/costModelParamNames.golden.txt
  with the same 53 new builtins already added to the Data variant

tasty-golden has a built-in --no-create flag that causes tests to fail
(rather than silently auto-create) when a golden file is missing.  This
makes it impossible for a test to pass in CI when its golden file was
accidentally omitted from the repository.

Changes:
* nix/project.nix: add testFlags = ["--no-create"] for every test
  component that uses tasty-golden (23 suites identified by running each
  suite with --help and checking for the flag in the output).
* .github/workflows/nightly-testsuite.yml: pass --no-create to the two
  nightly nix run invocations (plutus-core-test, plutus-ir-test).
* plutus-ledger-api: update costModelParamNames golden file, which was
  found to be stale (missing 23 new builtins) when running the test
  suite under --no-create during development of this fix.

Missing 53 new builtins: expModInteger, dropList, array ops (lengthOfArray,
listToArray, indexArray), BLS multi-scalar-mul, insertCoin, lookupCoin,
unionValue, valueContains, valueData, unValueData, scaleValue.

* Add generalized views with convenient syntax and Inhabitant class

* Generate malonzo

* Rename match constructor to match!

* Add some more motivation for the generalized views

* Generate MAlonzo

- Replace local isPubKeyAddress/isScriptAddress with
  toPubKeyHash/toScriptHash from PlutusLedgerApi.V1.Address
- Replace negateValue with PlutusTx.negate (Value has AdditiveGroup)
- Export and relocate currencySymbolFromHex and singleCurrencySymbol
  to a dedicated Helpers section at the bottom of Builder.hs
