Generate fixtures for these test cases for Amsterdam with:

fill -v tests/amsterdam/eip7928_block_level_access_lists/test_block_access_lists_invalid.py::test_bal_invalid_withdrawal_balance_value --fork Amsterdam

Test that clients reject blocks where BAL contains an incorrect balance value for an account modified only by a withdrawal.

Charlie receives a 10 gwei withdrawal in an empty block. BAL is corrupted by changing Charlie's post-balance to 999 instead of the correct 10_000_000_000 (10 gwei in wei).
