Move list/revoke your own PATs to Core

Problem to solve

In %13.3 we implemented APIs to allow admins to list PAT tokens of their users and optionally revoke tokens from their users.

In this first iteration, we did not delineate between the admin use case and user use case, which means these features are only available in GitLab Ultimate despite similar features, for users, being available in GitLab Core.

Proposal

1. Move both list and revoke API capabilities to GitLab Core

Further detail

This proposal does not move the admin capability out of GitLab Ultimate. Admins will still be required to have an GitLab Ultimate license to list and revoke the PATs of users within their instance.
