chisel injection into test function

[exp-table]

Component

Chisel

Describe the feature you would like

This feature would introduce the possibility to add a call such as vm.chisel() or vm.chiselBreakpoint() anywhere in a test function.

The desired behavior is that calling chisel on that function will result in the session being loaded with the entire state of the test at the time the call was made, including the storage state as well as the memory.

Running forge test should not result in a different behavior than usual.

Example

pragma solidity ^0.8.15;

import "forge-std/Test.sol";
import "forge-std/console.sol";
import "src/Kevin.sol";

contract KevinTest is Test {
    Kevin public kevin;

    function setUp() public {
        kevin = new Kevin();
    }

    function testKevin() public {
        uint256 bob = 15;
        vm.chisel();
        uint256 stewart = 1;
    }
}

Followed by chisel --match testKevin, which opens up a chisel session.
