justin 01eeb2f0d6 [ty] Support frozen dataclasses (#17974) ...

## Summary
https://github.com/astral-sh/ty/issues/111

This PR adds support for `frozen` dataclasses. It will emit a diagnostic
with a similar message to mypy

Note: This does not include emitting a diagnostic if `__setattr__` or
`__delattr__` are defined on the object as per the
[spec](https://docs.python.org/3/library/dataclasses.html#module-contents)

## Test Plan
