According to the spec [1], `current cues` and `other cues` should only contain cues from `hidden` or `showing` text tracks. In this patch, text track would be responsible to add `current cues` and `other cues` to the cues list by calling `GetCurrentCuesAndOtherCues()`. If the text track is disabled, then it won't add any cues to the cues list. In addition, in order to reduce the size of `other cues` (as actually we don't need to process all cues in the `other cues`), we use the time interval to only get the cues which are overlapping with the time interval.
