  feat(linalg): add a way to pass controlFn to `foldIntoPackUnpackPatterns` (#143685)

This PR adds a mechanism, so that downstream consumers can pass in
control functions for the application of these patterns. This change
shouldn't affect any consumers of this method that do not specify a
controlFn. The controlFn always gets the source operand of the consumer
in each of the patterns as a parameter.

In IREE, we (will) use it to control preventing folding patterns that
would inhibit fusion. See IREE issue
[#20896](https://github.com/iree-org/iree/issues/20896) for more
details.
