feat: rewrote the method for getting m2m objects

[VladislavYar]

Description

The _prefetch_m2m_relation method of the BaseExecutor class has been rewritten. Now objects are received directly through the specified queryset, which allows you to correctly use select_related, annotate, etc.

Motivation and Context

prefetch_related (m2m) functionality becomes like in Django.

How Has This Been Tested?

Added tests to tests/test_prefetching.py with verification of receiving data from annotate and select_related.
