dirstate-v2: Drop parent directory cache when removing a dirstate node

The premise of the directory cache is that the dirstate contains child nodes
for every entry that `read_dir` would return. When removing nodes, that may
not be the case anymore so the cache should be invalidated.

  $ touch subdir/unknown
  $ hg status
  ? subdir/unknown

  $ rm subdir/unknown
  $ hg status

Removing a node from the dirstate resets the cache for its parent directory

  $ hg forget subdir/a
  $ hg debugdirstate --dirs --no-dates | grep '^d'
  d   0          0 set                 subdir
  $ hg ci -qm '#1'
  $ hg debugdirstate --dirs --no-dates | grep '^d'
  d   0          0 unset               subdir
  $ hg status
  ? subdir/a

#endif
