typing: declare the `_phasesets` member of `phasecache` to be `Optional`

Something in this area got flagged while making the repository class visible to
pytype (instead of being typed as `Any`).  A None assignment to something not
optional is wrong, and when I tried setting it to `{}` to keep it non-Optional,
some tests failed.  There are checks for the attr being None elsewhere, so this
seems to have just been an oversight.

  $ hg bookmark -r0 '@'
  $ hg bookmark -r0 'a b c'
  $ hg bookmark -r0 'd/e/f'
  $ hg serve -n test -p $HGPORT -d --pid-file=hg.pid -A access.log -E errors.log
