auth: compute AuthUser.permissions lazily

Prepare for computing each kind of permissions separately so they can be
skipped in the common case.

This will undo a part of 1ecd6c0e2787 where we took the detour of assigning
permissions in __init__ - now we move it back to a LazyProperty, but in a
better way.
