[ty] dataclasses: Allow using dataclasses.dataclass as a function. (#18440)
## Summary

Part of https://github.com/astral-sh/ty/issues/111

Using `dataclass` as a function, instead of as a decorator did not work
as expected prior to this.
Fix that by modifying the dataclass overload's return type.

## Test Plan

New mdtests, fixing the existing TODO.

[ty] Synthetic function-like callables (#18242)
## Summary

We create `Callable` types for synthesized functions like the `__init__`
method of a dataclass. These generated functions are real functions
though, with descriptor-like behavior. That is, they can bind `self`
when accessed on an instance. This was modeled incorrectly so far.

[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
mdtest

[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.
