Remove event simulation of onChange events (#13176)

* Remove event simulation of onChange events

It’s time to get rid of even more `ReactTestUtils.Simulate`s. In this PR
we remove the event simulation from all onChange tests. To do this, we
have to get a setter to the untracked value/checked props.

All remaining `ReactTestUtils.Simulate` calls are either testing
ReactTestUtils or assert that they do/don't throw.

* Use input instead of change event for all but checkbox, radio, and select
