Describe the feature you would like

Currently, the mockCall() method can only return values. It would be useful to have a similar method called mockCallWithAction(), which takes in encoded calldata and address as additional parameter. For example, in ERC4626 vault's withdraw() method returns the asset amount as well as performs a transfer call which sends funds to the caller/recipient.

So, instead of just doing:

vm.mockCall(
  address(vault),
  abi.encodeWithSelector(IERC4626.withdraw.selector),
  true
);

We can do something like this:

struct Action {
  address target,
  bytes data
 }
  
bytes memory transferCalldata = abi.encodeWithSelector(IERC20.transfer.selector, receiver, 10e18);

Actions[] memory actions = new Action()[1];

actions.push({target: tokenAddress, data: transferCalldata});

vm.mockCallWithActions(
  address(vault),
  abi.encodeWithSelector(IERC4626.withdraw.selector),
  true,
  actions
);

It would also be nice to include actions the ability to trigger specific cheatcodes like deal(), etc.,

This would be super useful during integration testing. Happy to take this on. Let me know wdyt.
