  Log Message:
  -----------
  [mlir][linalg] Take artificial padding into account for pack/unpack folding. (#150272)

The revision only folds the tensor.pad/extract_slice op into
linalg.pack/unpack ops only when it is safe to fold. It is not valid to
have artificial padding.

The documentation improvement and verifier update will be done in a
separate PR (i.e., https://github.com/llvm/llvm-project/pull/149624).
The revision is a step towards it.
