Required permissions individually controlled on review

This change allows individual permission control when the
permissions review feature is enabled only for permissions
that are required to be individually controlled as opposed
to all permissions in the group.

Test: Manually interacted with each permission group that
has granularly controlled permissions. Verified from the
shell that permissions are correctly granted or revoked.
The UI also shows the correct messages based on the number
of granted granular permissions.
