in for, loop, while, auto print final value in each iteration (#7433)
# Description

Fixes: #7404 
Fixes: #7402 

## About change
In `eval_block`, all pipelines(or called statements?) result will be
printed except the last one, the last one is returned by `eval_block`
function.

So if we want to print the last statement in eval block, we just need to
print that value.

∙         break

∙         $total += 1
∙     }
∙     echo 3
∙ }
3
3
```

# Tests + Formatting

Don't forget to add tests that cover your changes.

Make sure you've run and fixed any issues with these commands:

- `cargo fmt --all -- --check` to check standard code formatting (`cargo
fmt --all` applies these changes)
- `cargo clippy --workspace -- -D warnings -D clippy::unwrap_used -A
clippy::needless_collect` to check that you're using the standard code
style
  - `cargo test --workspace` to check that all tests pass

# After Submitting

If your PR had any user-facing changes, update [the
documentation](https://github.com/nushell/nushell.github.io) after the
PR is merged, if necessary. This will help us keep the docs up to date.
