[ty] Support variable-length tuples in unpacking assignments (#18948)
This PR updates our unpacking assignment logic to use the new tuple
machinery. As a result, we can now unpack variable-length tuples
correctly.

As part of this, the `TupleSpec` classes have been renamed to `Tuple`,
and can now contain any element (Rust) type, not just `Type<'db>`. The
unpacker uses a tuple of `UnionBuilder`s to maintain the types that will
be assigned to each target, as we iterate through potentially many union
elements on the rhs. We also add a new consuming iterator for tuples,
and update the `all_elements` methods to wrap the result in an enum
(similar to `itertools::Position`) letting you know which part of the
tuple each element appears in. I also added a new
`UnionBuilder::try_build`, which lets you specify a different fallback
type if the union contains no elements.
