Update logging helpers to use new `tractor.log` API with `pkg_name=`
kwarg and add optional `tractor` "root logger" enabling.
Deats,
- change `piker.log.get_logger()` to use `pkg_name=` vs `_root_name=`.
- add `**tractor_log_kwargs` passthrough to both wrapper fns.
- add `with_tractor_log: bool` toggle to `.get_console_log()`.
- strip `'piker.'` prefix from logger names when present to avoid
newly added `tractor.get_logger()` warnings.
Surroundingly,
- add `subsys` import to `.clearing._ems` for log name
- update all `get_console_log()` calls to use `level=` kwarg
- add assertion checks for logger names in `_setup_persistent_emsd()`
Additionally,,
- fix all type annotations: `str|None` vs `str | None`.
- add multiline style to conditional in `.cli.services()`.
- drop unused `Optional` import from `._actor_runtime`.
- drop a few "blank lines" in various function sigs.
Warning: this patch will require an equivalent dev-commit at the time of
writing in `tractor` itself, for now the `piker_pin` branch should be
sufficient to avoid breakage 🙏!
