Added RunErrorDetails object for MaxTurnsExceeded exception (#743)
### Summary

Introduced the `RunErrorDetails` object to get partial results from a
run interrupted by `MaxTurnsExceeded` exception. In this proposal the
`RunErrorDetails` object contains all the fields from `RunResult` with
`final_output` set to `None` and `output_guardrail_results` set to an
empty list. We can decide to return less information.

@rm-openai At the moment the exception doesn't return the
`RunErrorDetails` object for the streaming mode. Do you have any
suggestions on how to deal with it? In the `_check_errors` function of
`agents/result.py` file.

### Test plan

I have not implemented any tests currently, but if needed I can
implement a basic test to retrieve partial data.

### Issue number

This PR is an attempt to solve issue #719 

### Checks

- [ ] I've added new tests (if relevant)
- [ ] I've added/updated the relevant documentation
- [ ] I've run `make lint` and `make format`
- [ ] I've made sure tests pass
