`prepare_deploy_contract` cheatcode

Proposal:

func ():
%{
  dep = Contract("./contract.cairo",  [1,2,3])
  start_prank(123, target=dep.contract_address)
  dep.deploy()
%}
end

Would work also for mock_call and any targeted cheatcode.

We could in the future deprecate deploy_contract, and instead use:

%{
  dep = Contract("./contract.cairo",  [1,2,3]).deploy()
%}

Interface

class Contract:
__init__(path, calldata): ...

def deploy(self) -> Contract: ...

We can create a mapping tmp_address -> actual_address, which could be updated by Contract::deploy just before deploying a contract.
