Piotr Mardziel 1b9001db47 core[patch]: preserve inspect.iscoroutinefunction with @deprecated decorator (#16295)
Adjusted `deprecate` decorator to make sure decorated async functions
are still recognized as "coroutinefunction" by `inspect`.

Before change, functions such as `LLMChain.acall` which are decorated as
deprecated are not recognized as coroutine functions. After the change,
they are recognized:

```python
import inspect
from langchain import LLMChain

# Is false before change but true after.
inspect.iscoroutinefunction(LLMChain.acall)
```
