Consider publishing Cats test helpers

[ceedubs]

@inthenow has raised some good suggestions (https://github.com/non/cats/pull/522#discussion_r39263357 and https://github.com/non/cats/pull/522#discussion_r39263505) for items in Cats tests that may be useful in other project that depend on Cats. Currently we are publishing laws but not some of our helpers like CatsSuite, (currently pending) CatsEquality, etc. We may not want to publish CatsSuite in its entirety, since then it becomes harder to change, but there may be useful elements worth extracting.

We should consider publishing such items.

As an advanced possible route forward, you may want to look at scala-bricks, and in particular scala-bricks test

CatsSuite could be very useful, but also favors ScalaTest. One question to consider is what useful test kit might be produced that plays well with all the major test frameworks.
