deploy_contract(ref self: ContractState, address: ContractAddress, deployer: ContractAddress, from_zero: bool, class_hash: ClassHash, calldata: Span<felt252>, salt: felt252) -> ContractAddress external

Deploys a contract through the Universal Deployer Contract.

When from_zero is false, salt is hashed with the caller address and the modified salt is passed to the inner deploy_syscall. This type of deployment is origin-dependent.

When from_zero is true, the deployment type is origin-independent.

Emits an ContractDeployed event.
