  [mlir] Add missing patterns to `linalg.decompose_pack_unpack` TD Op (#121400)

This PR is a follow-up to #116373 and #116439, where a Transform Dialect
(TD) operation was introduced to collect patterns for decomposing
tensor.pack. The second patch renamed the patterns and the TD Op.
Originally, adding patterns for `tensor.unpack` was marked as a TODO,
which this PR addresses.

No new tests are introduced in this PR. Instead, existing tests from:

* "decompose-tensor-unpack.mlir"

are reused. To achieve this:

* The test is updated to use the TD operation
  `transform.apply_patterns.linalg.decompose_pack_unpack` instead of the
  flag `--test-linalg-transform-patterns="test-decompose-tensor-unpack"`,
  avoiding artificial tests created solely for the TD Op.
* The TD sequence is saved to a new file, "decompose_unpack.mlir", and
  preloaded using the option.
