Allow field hooks to run onChange

[annardini]

I am trying to use a relationship field that when data is changed (onChange), automatically updates some read-only fields in an array in my collection. This is to prevent user error when trying to add them manually. However, Payload hooks only seem to run onSubmit so the user would have to save then go back and edit again which is not good UX. Haven't been able to find a work around yet but think it would be good to implement for at least some hooks like beforeChange, afterChange, beforeValidate and afterRead.

+1. I'm having a similar issue! I'm using dispatchField "ADD_ROW" on an array when the user selects something in a separate custom component and it successfully updates the data but the UI does not refresh until another change is made such as saving.
