[ty] Support **{...} unpacking in TypedDict constructors

[ty] Make dataclass `own_fields` a `salsa::tracked` method (#24620) ## Summary The lack of memoization here is leading to O(N^2) in at least one dataclass operation. If you trace `check_class`, we iterate over each member; then for dataclasses, for each member, we call `is_own_dataclass_instance_field`, which in turn calls `self.own_fields`. So for every member, we're re-creating the entire member map. I asked Codex to do some benchmarking -- here, with 1,000 fields: | Metric | Before | After | |---|---:|---:| | Wall time | 5.65s | 0.545s | | Max RSS | 113.45 MB | 87.52 MB | | Salsa memory report | 51.30 MB | 27.65 MB | If you increase to multiple thousands of fields, it generally doesn't finish on main (but takes ~1 second on this branch). As an alternative, we could rewrite the `check_class` pipeline to avoid the O(N^2) behavior, though we may end up just chasing down other usage sites (e.g., Codex suggests that `list_member.srs` also suffers from this as-is). Closes https://github.com/astral-sh/ty/issues/3190.

[ty] Respect mixed positional and keyword arguments in TypedDict constructor (#24448) ## Summary This PR ensures that we allow the following by adding a path for mixed positional and keyword arguments: ```python from typing import TypedDict class Base(TypedDict): name: str class ChildKwargs(TypedDict): name: str count: int def _(base: Base): ok_union_mapping = ChildKwargs(base, count=1) ``` Closes https://github.com/astral-sh/ty/issues/3225.

[ty] Add accidentally reverted liskov.md changes (#24643) ## Summary I'm sorry, I messed up while juggling too many branches, and (in merging https://github.com/astral-sh/ruff/pull/24636) accidentally reverted some changes that I made in response to a code review.
