Avoid recompiling every test that uses local Vm

### Component

Forge

### Describe the feature you would like

many tests in forge now use
```rust
prj.wipe_contracts();
prj.insert_ds_test();
prj.insert_vm();
prj.clear();
```

this clears the cache of the pre-compiled test project, which ruins the purpose of the forgetest_init macro, as well as making tests depend on ds-test which we have removed from forge-std long ago

we can surgically replace the forge-std Vm with the local one to have access to all the cheatcodes, or some other way so that we don't have to do this
