Before this change: * With legacy subtitle decoding (at render time), load errors (e.g. HTTP 404) would result playback completely failing, while parse errors (e.g. invalid WebVTT data) would be silently ignored, so playback would continue without subtitles. * With new subtitle decoding (at extraction time), both load and parse errors would result in playback completely failing. This change means that now neither load nor parse errors in text or metadata tracks stop playback from continuing. Instead the error'd track is disabled until the end of the current period. With new subtitle decoding, both load and parse errors happen during loading/extraction, and so are emitted to the app via `MediaSourceEventListener.onLoadError` and `AnalyticsListener.onLoadError`. With legacy subtitle decoding, only load errors are emitted via these listeners and parsing errors continue to be silently ignored. Issue: androidx/media#1722 PiperOrigin-RevId: 686902979
