1.1.5 merge spec tests (#2781)
* Fix arbitrary check kintsugi

* Add merge chain spec fields, and a function to determine which constant to use based on the state variant

* increment spec test version

* Remove `Transaction` enum wrapper

* Remove Transaction new-type

* Remove gas validations

* Add `--terminal-block-hash-epoch-override` flag

* Increment spec tests version to 1.1.5

* Remove extraneous gossip verification https://github.com/ethereum/consensus-specs/pull/2687

* - Remove unused Error variants
- Require both "terminal-block-hash-epoch-override" and "terminal-block-hash-override" when either flag is used

* - Remove a couple more unused Error variants
