Add ORCID to uploader/contributor of dataset

Overview of the Feature Request
In order to identify unique uploaders, we currently have to use strings. This means that Joe Smith, Joe S. Smith, Joe Samuel Smith, and J. S. Smith are all seen as different persons. We would like to add an ORCID so that we can quickly identify unique uploaders even if they use different spellings of their name.

What kind of user is the feature intended for?
(Example users roles: API User, Curator, Depositor, Guest, Superuser, Sysadmin)
This feature is intended for Curator, Depositor, Guest, Superuser, and Sysadmin.

What inspired the request?
We would like to have an accurate overview of depositors. This is currently difficult without extra (manual) cleaning.

What existing behavior do you want changed?
We want to change the fact that manual cleaning is necessary to identify unique uploaders. Adding ORCIDs to unique uploaders would make manual cleaning redundant.

Any brand new behavior do you want to add to Dataverse?
A field to add ORCIDs to depositors.

Any open or closed issues related to this feature request?
No.

Start by locating how uploader and contributor identities are represented and exposed for depositors, then trace the relevant data and user-role flows. Define where an ORCID field belongs and how it would identify the same person across name variations; the issue names no files, tests, or entry points to run.
