   Reviewed by Darin Adler.
   
   WebVTT cue text tokenizer algorithm has been updated to support
   all of HTML's character entities in w3c/webvtt#253.
   This patch updates the tokenizer to align with the latest spec.
   Spec: https://w3c.github.io/webvtt/#webvtt-cue-text-tokenizer
   
   The old `EscapeState` state for handling escape characters has been
   removed in favor of new two states. And the `WEBVTT_SWITCH_TO` operation
   has been added for the purpose of enabling state transition without
   the requirement to advance the input position.
