Message:

REST API: Do not allow access to users from a different site in multisite.

It has been unintendedly possible to both view and edit users from a different site than the current site in multisite environments. Moreover, when passing roles to a user in an update request, that user would implicitly be added to the current site.

This changeset removes the incorrect behavior for now in order to be able to provide a proper REST API workflow for managing multisite users in the near future. Related unit tests have been adjusted as well.

Props jnylen0, jeremyfelt, johnjamesjacoby.
Merges [40106] to the 4.7 branch.
Fixes #39701.
