fix: exclude EVM bytecode from production solc requests (#338)

This is to address issue #320

## Introduced changes
- Added new_required_for_tests() method that includes EVM bytecode flags
- Modified new_required() to exclude evm.bytecode and
evm.deployedBytecode
- Updated test utilities to explicitly request EVM bytecode when needed
