feat(trip-form): handle date/time state internally

[daniel-heppner-ibigroup]

This internal state handling will help us deal with some state problems when storing the state in the URL in OTP-RR.

Annoying, but seems to work. One important question before I can approve

[miles-grant-ibigroup]

Do implementers have to change this as well? If so this would be a breaking change no?

[daniel-heppner-ibigroup]

No they don't, this is just for the story because when it's set to NOW you don't get to see the actual date time selector. Ideally this would be a control in the story but the way we've set up the story here makes that difficult, should probably redo that at some point.

[miles-grant-ibigroup]

Ah I see. Ok looks good!

@miles-grant-ibigroup can we remove the legacy code? I didn't touch it but actually I think it would need to be changed here as well if we're not going to remove it. Can you check into browser support? https://caniuse.com/input-datetime

I checked feel free to remove

Still feels scary... but onwards and upwards!
