[dataclass_transform] support class decorator parameters (#14561)
The initial implementation of `typing.dataclass_transform` only
supported the no-argument `@decorator` form; this adds support for the
`@decorator(...)` form supporting the same arguments we support for
`dataclasses.dataclass`. This also matches the list of arguments
specified in PEP 681.
