[ty] Return Option<TupleType> from infer_tuple_type_expression (#19735)
## Summary This PR reduces the virality of some of the `Todo` types in `infer_tuple_type_expression`. Rather than inferring `Todo`, we instead infer `tuple[Todo, ...]`. This reflects the fact that whatever the contents of the slice in a `tuple[]` type expression, we would always infer some kind of tuple type as the result of the type expression. Any tuple type should be assignable to `tuple[Todo, ...]`, so this shouldn't introduce any new false positives; this can be seen in the ecosystem report. As a result of the change, we are now able to enforce in the signature of `Type::infer_tuple_type_expression` that it returns an `Option<TupleType<'db>>`, which is more strongly typed and expresses clearly the invariant that a tuple type expression should always be inferred as a `tuple` type. To enable this, it was necessary to refactor several `TupleType` constructors in `tuple.rs` so that they return `Option<TupleType>` rather than `Type`; this means that callers of these constructor functions are now free to either propagate the `Option<TupleType<'db>>` or convert it to a `Type<'db>`. ## Test Plan Mdtests updated.
