Fix EOA check for precompiles

[RomarQ]

Implements a new method on the precompile handler to obtain the addresses of contracts being constructed.

This is necessary because contracts under-construction don't have code, the code will only be added to storage after the init_code is executed.

Address type heuristics:

• It is a smart-contract if the address is a contract being constructed;
• It is a Precompile if calling pallet_evm::Config::PrecompilesValue::get().is_precompile returns true;
• It is a EOA when the address does not have code;
• If neither of the conditions above are true, we assume that an address is a smart-contract.

Also, this is already part of the changes required for supporting https://eips.ethereum.org/EIPS/eip-7702, which is part of the Pectra upgrade.
