> Add deterministic coders for common Python types

> FastPrimitivesCodeImpl has "fallback" deterministic encoding of certain types
> in encode_special_deterministic. This encoding is not as efficient as a
> type-specific coder (https://github.com/apache/beam/pull/14455).
> This bug is to implement type-specific coders for the types supported in
> encode_special_deterministic. This method will still handle encoding for
> cases in which type information is not available, and the new coders will be
> used where type hints are available.
> Types to implement coders for: enum.Enum, dataclasses.dataclass,
> collections.namedtuple / typing.NamedTuple (verify there's no
> conflict/duplication with RowCoder)
