Using chunkless preparation greatly improves start up time if the master playlist declares CODECS for the renditions. Hence, we turn this on by default as it benefits most well-defined HLS master playlists. The only known reason why developers may want to turn this feature off is when the renditions contain muxed closed-caption tracks that are not declared in the master playlist. So this change also updates the documentation and RELEASENOTES to point out this caveat. PiperOrigin-RevId: 413950036
