Mason Daugherty 6199525f50 perf(core): defer specific langsmith imports to reduce import time (#35298) ...

Defer `langsmith` and tracer imports in `callbacks/manager.py` and
`runnables/config.py` from module-level to function-level.

These imports pull in the full `langsmith` package (~132ms) at import
time but are only used inside `_configure()`, `trace_as_chain_group()`,
`_set_config_context()`, and `set_config_context()` — none of which run
during module initialization.
