Stanislau Hlebik a47bb8c5e1 mononoke: use caching in phases more efficiently
Summary:
Our phases caching wasn't great. If you tried to ask for a draft commit then
we'd call mark_reachable_as_public method, bu this method was bypassing
caches.

The reason why we had this problem was because we had caching on a higher level
than necessary - we had SqlPhases struct which was "smarter" (i.e. it has a
logic of traversing ancestors of public heads and marking these ancestors and
public) and SqlPhasesStore which just did sql access. Previously we had our
caching layer on top of SqlPhases, meaning that when SqlPhases calls
`mark_reachable_as_public` it can't use caches anymore.

This diff fixes it by moving caching one layer lower - now we have a cache
right on top of SqlPhasesStore. Because of this change we no longer need
CachingPhases, and they were removed. Also `ephemeral_derive` logic was
simplified a bit
