Abhijeet Prasad Bodas 68b0386007 [ty] Implement DataClassInstance protocol for dataclasses. (#18018 )

Fixes: https://github.com/astral-sh/ty/issues/92

## Summary

We currently get a `invalid-argument-type` error when using
`dataclass.fields` on a dataclass, because we do not synthesize the
`__dataclass_fields__` member.

This PR fixes this diagnostic.

Note that we do not yet model the `Field` type correctly. After that is
done, we can assign a more precise `tuple[Field, ...]` type to this new
member.

## Test Plan
New mdtest.
