obsolete: avoid using revset language to compute the obsolete revset

This is part of a refactoring that moves some phase query optimization from
revset.py to phases.py. See previous patches for the motivation.

Now we have APIs in phasecache to get the non-public set efficiently, let's
use it directly instead of going through the "not public()" revset language
in "obsolete()" computation.

This patch was meaured using:

  for i in 'public()' 'not public()' 'draft()' 'not draft()'; do
      hg perfrevset "$i"; hg perfrevset "$i" --hidden;
  done

and no noticeable (> 1%) performance difference was observed.
