Test Bls12 Variable Length Input Contracts

Documentation for tests/prague/eip2537_bls_12_381_precompiles/test_bls12_variable_length_input_contracts.py.

Generate fixtures for these test cases for Prague with:

Prague only: 

fill -v tests/prague/eip2537_bls_12_381_precompiles/test_bls12_variable_length_input_contracts.py --fork=Prague --evm-bin=/path/to/evm-tool-dev-version
For all forks up to and including Prague: 
fill -v tests/prague/eip2537_bls_12_381_precompiles/test_bls12_variable_length_input_contracts.py --until=Prague --evm-bin=/path/to/evm-tool-dev-version

Tests minimum gas and input length for BLS12_G1MSM, BLS12_G2MSM, BLS12_PAIRING precompiles of EIP-2537: Precompile for BLS12-381 curve operations

Tests minimum gas and input length for BLS12_G1MSM, BLS12_G2MSM, BLS12_PAIRING precompiles of EIP-2537: Precompile for BLS12-381 curve operations.

test_valid_gas_g1msm(state_test, pre, post, tx)

Test the BLS12_G1MSM discount gas table in full, by expecting the call to succeed for all possible input lengths because the appropriate amount of gas is provided.

If any of the calls fail, the test will fail.

Test the BLS12_PAIRING precompile, by expecting the call to fail for all possible input lengths (up to k == PAIRINGS_TO_TEST) because the incorrect input length was used.

If any of the calls succeeds, the test will fail.
