Pull in CwlCatchException and CwlPreconditionTesting transitively. (#1108)

* CwlCatchException and CwlPreconditionTesting dropped carthage support

Stop embedding them, and pull them in through SPM or Cocoapods transitively.

* Avoid checking in the carthage directory

* Fix podspec lint errors

* Add specific error messaging when trying to use throwAssertion on watchOS/tvOS and cocoapods

* Add github action to verify that carthage still builds

* (re)add verbose logging to podspec and carthage tests
