Subject: refactor(preg): make preg_grep() return an iterator

Callers had to build a temporary Vec<&str> at every call site to satisfy
the &[&str] parameter. Taking IntoIterator and yielding the matched items
lets them pass owned or borrowed strings directly.

The flags variant and PREG_GREP_INVERT go away with it: no caller passes
flags, and Composer's Preg::grep() has no such parameter either.
