Allow meeting admin user to update a non admin user that shares all his meetings with requesting user.

Closes #2522

[hjanott]

Discussed with @Elblinator that it should be sufficient for the client to only have a presenter that returns true if a user can be edited. An issue for the client needs to be created anyway. The existing get_user_scope presenter will be obsolete and deleted at a later point of time. Relevant group permissions are user.can_update and user.can_manage.

The client counterpart is the following Issue: https://github.com/OpenSlides/openslides-client/issues/3841

I tested the PR with different scenarios and sometimes the backend returns Errors even though the action should be permitted. What I did:

• Create three meetings
• Add A always as admin to all meetings
• Add B groups do not seem to matter, I could not find a connection at least
• Try changing B's personal information with A sometimes, and only sometimes, while trying to change the personal information B's personal information is not changed but an Error that A is missing the user.canUpdate permissions for he meetings {1,2,3}
