Reduce cached SQL queries in /api/v4/internal/pages endpoint
What does this MR do and why?
Previously VirtualDomain#pages_access_control_trie dominated the CPU
profile because the memoization was not working properly. It was being
memoized with the value of self_and_descendants, which is a different
object ID each time the method is called. Fix this by memoizing
pages_access_control_trie directly.
