The joined behavior in `containsInOrder` has some usability issues:
- It mimics the arguments for `deepEquals`, but it doesn't have the same
  behavior for collection typed elements. Checking that a nested
  collection is contained in order requires a `Condition` callback that
  uses `.deepEquals` explicitly.
- The `Object?` signature throws away inference on the `Condition`
  callback arguments. With a method that supports only conditions the
  argument type can be tightened and allow inference.

Also deprecate `pairwiseComparesTo`.

The prior version would accept the `0` as meeting the conditions.
