phases: invalidate the phases set less often on retract boundary

We already have the information to update the phase set, so we do so directly
instead of invalidating the cache.

This show a sizeable speedup in our `perf::unbundle` benchmark on the
many-draft mozilla-try repository.

Check same result using `experimental.extra-filter-revs`

  $ hg -R test --config experimental.extra-filter-revs='not public()' serve -p $HGPORT1 -d --pid-file=hg2.pid -E errors.log
  $ cat hg2.pid >> $DAEMON_PIDS
  $ hg -R test2 incoming http://foo:xyzzy@localhost:$HGPORT1/
  comparing with http://foo:***@localhost:$HGPORT1/

  $ cat errors.log

Check the behavior is other filtered revision exists

add more content and complexity to the repository too

  $ hg -R test debugbuilddag '+6:branchpoint.:left+4*branchpoint.:right+5' --from-existing
  $ hg -R test phase --public 'desc("re:^r11$")'
  $ hg -R test phase --secret --force 'desc("re:^r9$")'
