[ty] Infer list[T] when unpacking non-tuple type (#18438)
## Summary

Follow-up from #18401, I was looking at whether that would fix the issue
at https://github.com/astral-sh/ty/issues/247#issuecomment-2917656676
and it didn't, which made me realize that the PR only inferred `list[T]`
when the value type was tuple but it could be other types as well.

This PR fixes the actual issue by inferring `list[T]` for the non-tuple
type case.

## Test Plan

Add test cases for starred expression involved with non-tuple type. I
also added a few test cases for list type and list literal.

I also verified that the example in the linked issue comment works:
```py
def _(line: str):
    a, b, *c = line.split(maxsplit=2)
    c.pop()
```

Markdown files within the mdtest/ subdirectory are tests of type inference and type checking; executed by the tests/mdtest.rs integration test.

See crates/ty_test/README.md for documentation of this test format.
