EXTCODEHASHonly needs the account’s emptiness status and code_hash, not the full bytecode. Previously we were callingload_account_info_skip_cold_load and
berlin_load_account!with load_code = true, which forced bytecode loading from the database even though extcodehash only reads is_empty() and code_hash. This change switches both branches to use load_code = false, so we no longer pull code blobs into memory. The cold/warm account accounting and gas behaviour are unchanged, and the implementation remains consistent with EIP-1052/EIP-161 semantics while reducing unnecessary IO and allocations.
