Privacy: Un-map privacy capabilities to make them available to be assigned for custom roles:

* `erase_others_personal_data`
* `export_others_personal_data`
* `manage_privacy_options`

Previously mapped to `manage_options` or `manage_network` (on Multisite), these are now added to the Administrator role separately.

Additionally, `manage_privacy_options` is added to the Editor role.
