Merge #18514: test: remove rapidcheck integration and tests

9e071b00898aedd9632f105a22d976dc6dbc84b1 test: remove rapidcheck integration and tests (fanquake)

Pull request description:

  Whilst the property tests are interesting, ultimately [rapidcheck](https://github.com/emil-e/rapidcheck) integration in this repository has not gained much traction. We have a limited number of tests, and they are rarely (if ever) run. Have discussed this with Chris Stewart.
