Change LegacySubtitleUtil handling of SubtitleParser.OutputOptions
If the `Subtitle` has 'active' cues at `OutputOptions.startTimeUs`, this change ensures these are emitted in a `CuesWithTiming` with `CuesWithTiming.startTimeUs = OutputOptions.startTimeUs`. If `OutputOptions.outputAllCues` is also set, then another `CuesWithTiming` is emitted at the end that covers the 'first part' of the active cues, and ends at `OutputOptions.startTimeUs`. As well as adding some more tests to `LegacySubtitleUtilWebvttTest`, this change also adds more tests for `TtmlParser` handling of `OutputOptions`, which transitively tests the behaviour of `LegacySubtitleUtil`. #minor-release PiperOrigin-RevId: 573151016
