Make backtracking modifiers on alternations work correctly #368

  1. Make || alternations respect :ratchet mode 

    :ratchet mode already stopped the regex engine from backtracking
into quantifiers and `|` (LTM) alternations.

Now it also stops it from backtracking into `||` (sequential)
alternations.

(Fixes RT #130117)

  2. Allow per-atom backtracking modifiers to override :ratchet 

    (This fixes RT #131973.)
