Tests gas usage on point evaluation precompile for EIP-4844: Shard Blob Transactions

Test gas usage on point evaluation precompile for EIP-4844: Shard Blob Transactions.

test_point_evaluation_precompile_gas_usage(state_test, pre, tx, post)

Test point evaluation precompile gas usage under different call contexts and gas limits:

• Test using all call types (CALL, DELEGATECALL, CALLCODE, STATICCALL)
• Test using different gas limits (exact gas, insufficient gas, extra gas)
• Test using correct and incorrect proofs
