fix(tests): enhance & un-skip Amsterdam ported static SSTORE, refund & misc tests (Pt. 2c)

[spencer-tb]

Description

Third slice of the Part 2 ported static split (chain in #3264): SSTORE, refund, and miscellaneous families — stSStoreTest plus the gas_cost SSTORE case, refund600 and the refund-cap formula, stSolidityTest, stTransactionTest, attack-replay + callcode-suicide, double-selfdestruct-touch, exp-empty / homestead-oog / create-warmth, and gas-price-for-codes + memory OOG. 21 files, 37 skip-list entries un-skipped (86 → 49).

Notables: the EIP-3529 refund-cap base needs return_cost_deducted_prior_execution=True; a post-call SSTORE on a 1/64 retention needs the sentinel-prewrite recipe (EIP-2200 stipend vs retention); the Ropsten attack-replay loop drains after 22 children instead of 123 under EIP-8037 with the revised EIP-8038 pricing (split post pins both counts); reservoir-less sub-calls pay state gas from their own grant, and a failed frame forfeits the whole grant.

Every touched test fills green across its full valid_from range, and the whole tests/ported_static/ tree fills green on Amsterdam at this slice. Stacked on Pt. 2b (#3320); the diff includes the earlier slices until they merge.
