bpo-37207: Use vectorcall for range() (GH-18464)
This continues the `range()` part of #13930. The complete pull request is stalled on discussions around dicts, but `range()` should not be controversial. (And I plan to open PRs for other parts if this is merged.)
On top of Mark's change, I unified `range_new` and `range_vectorcall`, which had a lot of duplicate code.
