Add HLS playback test with TTML subtitles muxed into MP4
The test is hidden behind the `@Ignore` annotation due to some flakiness. However, it will be removed when the subtitle parsing is moved to a pre-sample-queue architecture. The test media was created with: ```shell $ cp ../../dash/standalone-ttml/sample.xml sample.ttml $ MP4Box -add sample.ttml sample.text.mp4 $ MP4Box -frag 10000 sample.text.mp4 $ rm sample.ttml ``` PiperOrigin-RevId: 582347113
