В репозитории больше не будет `__pycache__` при запусках через ya make / test

На примере devtools/ya/handlers/analyze_make/tests
Время конфигурации в горячем сценарии в режиме --ext-py при изменении одного питонфайлика: `Configure time - 6.1 s`
Время конфигурации в горячем сценарии в режиме --ext-py при изменении одного питонфайлика с текущими правками: `Configure time - 4.6 s`

Режим позволяет перезапускать python тесты или интеграционные тесты на питон программы при внесении изменений в python файлы без перекомпиляции.

Сценарий:
- прогнали тесты
- внесли изменение в `library/python/func/__init__.py`
- перезапустили, смотрим на времена

На примере интеграционного devtools/ya/handlers/analyze_make/tests в codenv (base конфигурация).

В новом режиме тест ожидаемо замедляется, так как все питон программы при каждом старте вынуждены читать файлы с фс (ещё через арк), а потом ещё и компилировать байткод, т.е. холодный запуск

There is no runtime perf impact, but
- The change reduces build graph by removing 2 nodes out of 5 for python which accelerates both configuration and build
- surprisingly in all experiments there were positive impact on binary size about 2MiB
