  [mlir][linalg] Update pack and unpack documentation (#143903)

* Clarified the `inner_dim_pos` attribute in the case of high
dimensionality tensors.
* Added a 5D examples to show-case the use-cases that triggered this
updated.
* Added a reminder for linalg.unpack that number of elements are not
required to be the same between input/output due to padding being
dropped.

I encountered some odd variations of `linalg.pack` and `linalg.unpack`
while working on some TFLite models and the definition in the
documentation did not match what I saw pass in IR verification.

The following changes reconcile those differences.
