Optimize logging package import overhead with lazy imports #156777
Description
import logging.config costs ~29 ms and import logging.handlers ~26 ms, but most of what they
import is only needed conditionally based on feature usage (socket/HTTP/SMTP
handlers, the config socket listener, multiprocessing queue detection).
Apply lazy imports to the modules within the logging package while preserving finalization and shutdown expectations.

@hugovk can this issue be a sub-issue of #154675
(I don't think I have the permissioning to do so)

Done! Any future import improvements can use that issue directly.
