refactor(test-benchmark): migrate benchmark suite to devnet-8

[LouisTsai-Csie]

Description

Makes tests/benchmark/ devnet-8 ready.

• Bumps the benchmark EVM pin to glamsterdam-devnet-8.
• Fixes loop and transaction sizing that assumed devnet-7 gas values, so the affected benchmarks fill their gas target again.
• Revives test_block_full_access_list_and_data, which was skipped on every fork with an EIP-7934 block RLP size limit.
• Derives the remaining hardcoded gas amounts and docstring values from the fork.
