Extend support pyi files

Сейчас pyi файлы в макросе PY_SRCS используются исключительно в Arcadia плагине для продуктов JB, при сборке эти файлы просто игнорируются.

В этом PR добавил шаг, который  будет содержимое этих файлов складывать в ресурсы, секция PY_SRCS удобна тем, что позволяет раскладывать pyi файлы с учетом TOP_LEVEL/NAMESPACE, а это необходимо для правильной работы mypy.
