Returns a decorated wrapper around the function that validates the arguments and, optionally, the return value.
Usage may be either as a plain decorator `@validate_call` or with arguments `@validate_call(...)`.
Args:
__func: The function to be decorated.
config: The configuration dictionary.
validate_return: Whether to validate the return value.
Returns:
The decorated function.
