Update the DataTable Row Cell data model

[ajdaniel]

Detailed description

As of the discussion in #737 the data model for a row cell in DataTable ought to be updated to a new structure:

{
  id: string,
  value: any,
  state: {  // new stuff
    isEditable: boolean,
    isEditing: boolean,
    isValid: boolean,
    errors: Array<CellError>,
  },
  info: {
    header: string,
  },
}

If the structure of existing properties change, this will be a breaking change. We could either put this change in a major release, or better yet, have this structure, which has the old and new model, but should indicate the old model is now deprecated, and will be removed in the next major release.

{
  id: string,
  value: any,
  isEditable: boolean, // deprecated
  isEditing: boolean, // deprecated
  isValid: boolean, // deprecated
  errors: Array<CellError>, // deprecated
  state: {  // new stuff
    isEditable: boolean,
    isEditing: boolean,
    isValid: boolean,
    errors: Array<CellError>,
  },
  info: {
    header: string,
  },
}

Hi @ajdaniel! 👋 Thanks so much for taking the time to write this out. We really appreciate it 🙌

Definitely think we can introduce this stuff in soon, and just deprecate access to the other fields with a warning message until the next major release.
