Andy Young 625ed0ee8c fix(openai): guard httpx finalizers (#37570 )

Same shape as the merged anthropic patch in #37064, ported to
`libs/partners/openai`.

`_SyncHttpxClientWrapper.__del__` / `_AsyncHttpxClientWrapper.__del__`
check `self.is_closed`, which reads `self._state`. When a wrapper is
created without `__init__` running to completion — `copy.deepcopy` via
`__new__` + `__setstate__`, or a constructor that raised partway through
— `_state` is missing and the finalizer prints

```
Exception ignored in: <function _SyncHttpxClientWrapper.__del__ at 0x...>
Traceback (most recent call last):
  File ".../langchain_openai/chat_models/_client_utils.py", line 366, in __del__
    if self.is_closed:
  File ".../httpx/_client.py", line 228, in is_closed
    return self._state == ClientState.CLOSED
AttributeError: '_SyncHttpxClientWrapper' object has no attribute '_state'
```

at GC time. Same noise pattern that #37064 fixed for the anthropic
partner.

Hoist the `is_closed` access inside the existing `try/except` so the
`AttributeError` is swallowed alongside the `close()` / `aclose()`
exceptions that block already handles.

Tests: two new unit tests build the wrappers via `__new__` (no
`__init__` → no `_state`) and call `__del__` directly, mirroring the
tests added in #37064.

Verified:
- `cd libs/partners/openai && make format` -> all checks passed
- `cd libs/partners/openai && make test
TEST_FILE=tests/unit_tests/chat_models/test_client_utils.py` -> 37
passed, 1 skipped (linux-only)
- `cd libs/partners/openai && make lint` -> all checks passed, mypy
clean
