Mason Daugherty 2cff369cdc feat(anthropic): accept TypedDict for built-in tool types (#34279 )

Widen `bind_tools` to accept `TypedDict` via `Mapping` so that users may
import and use Anthropic's built-in tool types:

```python
import subprocess

from anthropic.types.beta import BetaToolBash20250124Param
from langchain.tools import tool

tool_spec = BetaToolBash20250124Param(
    name="bash",
    type="bash_20250124",
    strict=True,
)

@tool(extras={"provider_tool_definition": tool_spec})
def bash(*, command: str, restart: bool = False, **kw):
    """Execute a bash command."""
    if restart:
        return "Bash session restarted"
    try:
        result = subprocess.run(
            command,
            shell=True,
            capture_output=True,
            text=True,
            timeout=30,
        )
        return result.stdout + result.stderr
    except Exception as e:
        return f"Error: {e}"

# Bind bash tool to your model
```
