Adds an end-to-end test for `tensor.unpack` with dynamic inner tile sizes. While relatively simple (e.g., no vectorization), this example required a few fixes in handling `tensor.unpack` (and similar fixes for `tensor.pack` before that): * #119379, #121393, #121400. The end goal for this test is to incrementally increase its complexity and to work towards scalable tile sizes. Note, this PR complements #115698 in which similar test for `tensor.pack` was added.
