* validate EL block hash when running consensus block tests
We currently don't have an easy way to test EL block hash computation.
As the EL block hash in consensus-spec-tests is computed correctly,
update the test runners that load block from test files to also verify
the EL block hash. This increases missing test coverage.
Requires https://github.com/ethereum/consensus-specs/pull/3829
* fix
* resolve merge conflicts
* fix genesis case, and deal with `incorrect_block_hash` test
* add missing export marker
* fix import
* htr mutates underlying data, messing with differ, create copy in test
* Handle payloads with empty tx (unsupported in ordered trie tool)
* Update copyright years
