Validate the doc dictionary based on the given typed dictionary specification spec.

Arguments:

• spec _Type[TypedDict] - The typed dictionary that doc should conform to.
• doc StrAny - The dictionary to validate.
• path str - The string representing the location of the dictionary in a hierarchical data structure.
• filter_f TFilterFunc, optional - A function to filter keys in doc. It should return True for keys to be kept. Defaults to a function that keeps all keys.
• validator_f TCustomValidator, optional - A function to perform additional validation for types not covered by this function. It should return True if the validation passes or raise DictValidationException on validation error. For types it cannot validate, it should return False to allow chaining. Defaults to a function that rejects all such types.
