Implement latest and earliest methods for a queryset

[ruitcatarino]

Description

This implements the latest (https://docs.djangoproject.com/en/5.1/ref/models/querysets/#latest) and earliest (https://docs.djangoproject.com/en/5.1/ref/models/querysets/#earliest) methods similar to Django.

Motivation and Context

Like I explained in the issue #1753 I miss these two methods as someone coming from Django.

How Has This Been Tested?

Well I implemented tests to validate the usage of both and ran them with make test. I also did some local testing.

Can you please add few test about passing related fields there?
Like related_model__pub_date

I understand that it is not a prime usecase for that, but if we are supporting that behaviour - would be nice to have it covered

I've added more tests to increase coverage, including testing the use of related fields tests/test_latest_earliest.py
