Automatically reset forms after action finishes (#28804)
This updates the behavior of form actions to automatically reset the form's uncontrolled inputs after the action finishes. This is a frequent feature request for people using actions and it aligns the behavior of client-side form submissions more closely with MPA form submissions. It has no impact on controlled form inputs. It's the same as if you called `form.reset()` manually, except React handles the timing of when the reset happens, which is tricky/impossible to get exactly right in userspace. The reset shouldn't happen until the UI has updated with the result of the action. So, resetting inside the action is too early. Resetting in `useEffect` is better, but it's later than ideal because any effects that run before it will observe the state of the form before it's been reset. It needs to happen in the mutation phase of the transition. More specifically, after all the DOM mutations caused by the transition have been applied. That way the `defaultValue` of the inputs are updated before the values are reset. The idea is that the `defaultValue` represents the current, canonical value sent by the server. Note: this change has no effect on form submissions that aren't triggered by an action. DiffTrain build for commit 41950d1.
