Required new tests due to max gas limit reduction

Includes a list of tests that have to be enhanced or implemented due to the max transaction gas limit rendering some static tests unable to run:

- [ ] `tests/static/state_tests/Cancun/stEIP1153_transientStorage/21_tstoreCannotBeDosdOOOFiller.yml`: Test `tests/benchmark/test_worst_compute.py::test_worst_tstore` needs to add a small change so the key to the TSTORE operation keeps swapping between values closer to 2**256 and values closer to 0 (need to add `Op.SUB(0, Op.GAS)` to the key on top of simple `Op.GAS`).
- [ ] New test to `tests/benchmark/test_worst_blocks.py` with blocks full of authorizations.
- [x] New benchmark test to max out blake2 usage in multiple transactions (see `tests/istanbul/eip152_blake2/test_blake2.py::test_blake2b_gas_limit`)
- [x] Port `tests/prague/eip2537_bls_12_381_precompiles/test_bls12_pairing.py` to a multi-tx benchmark test.
