Field visibility access is not applied correctly due to caching

Problem/Motivation

Field visibility access is not applied correctly due to caching.

Steps to reproduce

• Create role X.
• Give role X the permissions to "view user information" and "Set own profile fields visibility".
• Create user A and user B.
• Assign role X to both users (Users should have same role(s)).
• Add a field (e.g. Name) to user entity type.
• Login as user A, allow other users to view your Name, enter your Name and then immediately visit your own profile page. You should see your Name (Perfect!).
• Login as user B, visit user A profile, you should see the Name of user A (Perfect!).
• Now login again as user A, do NOT allow other users to view your Name, then save and visit your own profile page. You should see your Name (Perfect!).
• Now login again as user B, visit user A profile, you see user A name (NOT GOOD!).
• Clear cache, and then as user B, visit user A profile, then you don't see user A Name (Perfect!)
• Now login as user A, and visit your own profile, then you don't see your own Name (NOT GOOD!)

Proposed resolution

Could be solved by applying the patch in 🐛 Cache metadata by plugins is discarded Needs review and do the necessary changes to user_fields_visibility field permission type plugin.
