Subject: refactor(preg): merge preg_replace_callback2 into
 preg_replace_callback

preg_replace_callback2 had one caller, Preg::replace_callback6, which
was itself reached only from Preg::replace_callback with the default
limit, count and flags. Fold the two shim functions into one and drop
those parameters along with replace_callback6.

The surviving callback takes callback2's IndexMap of matches: it can be
keyed by group name, and it omits trailing non-participating groups the
way PHP does, which is what the callbacks in Process and ProgressBar
test for.
